Evaluate the two expressions and compare the answers. Do the expressions have the same value? (See Example 2.) $$\left(\frac{3}{10}\right)^{2} \text { and }(0.3)^{2}$$

This question is from Paulina Milson. Properties of excellence here that wrote answer in question was given us one destruction seven were 10. Thank you. Another told me you weren't. She went to the artery. We have to leave while you're trying to compare. How do evaluate and compare? Yeah, See here. Seven back then. Party men one number two returning the inside the parenthesis. It means message. Multiple or into 13. 7 by 10 multiplied 7. 13 This number multiple trips 7. 30. When I multiply Jackson's we have to multiply the numerator with numerator and the denominator. So here, 10 in returning to then and we got the result Touch 37 to 7. 49 7 3 43. Where the way here One told you. We heard the value here. Right? 123 43 way. Want Children now Come to the national number. Yeah, you're a point seven. Do three anyone number is returning center for also the same things, but as it just means European seven multiple within 0.7. Also it little principle, any multiplies and the simple numbers Forget about the decimal. Well, just multiplayer seven number seven or seven so the number will get seven. Multiple seven again. 49 in 27 This is three for three. This is three, 43 and very traditional point C After here, after the small 0.0.1 digit is here. And here also one digital here one little So 30 years serious only from right said we have to count. 123123 So we have reported a small point here. Right over here. Such answer is 0.343 Both expressions have same. Helly, If we convert this decimal number into Faxon also, you get the same number of 3. 43 by 1000, or we convert distraction 3. 43 by 1000 into the small number will get a 0.3 for three listening. So both her same hell what we can say. What expressions have same value? Yes. You don't? Yeah. Thank you.

Here in this question one by two to the par three and one way to the directory. Oh, your value to value. Yes, there to express and have same. Hello. These two have, Sam. Hello? Yes, how here in this question one by two with parenthesis three. And how do you know? An exponentially. What expression? With the apology Best did retain with parenthesis around the base. So judge one way to get the part three to follow this we have one by two, one by two. And one by two. So this age one by eight, we got the value of one by eight to to to and to also this would a parenthesis one boy total liberal tree. Same thing if there is no parenthesis. The expressions one by two Q each the same of one were to Q war. You could violently one way two into two into this is one way. Eight. So both have the same value. Here he is both her Sam. Hello.

Lesson number 130 were given to expressions. And to find out the truth presence attitude went out. Let's see what other expressions question this person is, I'm sure. Last four. Another night. The first person to find direct student to find that the century current or not, to find the cramps. And it's at its base. The board. This business of same tops them very good. That is part of the towns and budget species. There it is fine, it's hard to. And four here it is. I can see you get one resistance fighter and there is no fun. Good Mid East Side. So it's not. It is, for there is no force. Here it is nine there. There's no nine different. So towns are not the same in both experiencing. So okay, let me say this. Not Cuba is the fundamental expression by your grass for and manager and not the cure in Egypt. Thank you.

And his problems is to tell whether these two expressions are equivalent. So 63 a b over seven a. And we're comparing that to the expression nine times a Times B. Well, if we look at our left expression since the right expressions already simplified, let's just simplify it. So we have 63 divided by seven. That's just gonna be nine. We have a divided about a So it about about a just one and by the identity property property multiplication. We can put a one under here, and then we just multiply that by be over one, which is just be so again by the identity property of multiplication. This side's just nine b, which is not equivalent to nine times eight times be so. These two expressions are not equivalent time. Thank you very much.
