Using complete sentences, explain the steps in simplifying the expression of each student and identify who is correct.

I know the question is not there , I was typing it out .

@LaynaMae the Khan Academy is a good source for students.

Make use of the following identities: $\Large \frac{ a^m }{ a^n } = a^{m-n} ; \quad a^m*a^n = a^{m+n};$$\Large (a^m)^n = a^{mn}; \quad \sqrt[n]{a} = a^{\frac{ 1 }{ n }}$

also $$(ab)^m=a^m*b^m$$

9. LaynaMae

Okay .... well that doesn't really help me much with the question itself :(

11. LaynaMae

@amistre64 ? :(

12. LaynaMae

@ash2326 ?

13. amistre64

the properties of exponents have already been presented to you. the problem itself is just messy looking

14. LaynaMae

Very ..

15. amistre64

the good news is that they are pretty much all fractions with a 4 underneath what is 5+7-1? what is 3+5-8? what is 12/3? what is 1+5+9+1?

16. amistre64

second one i mistyped: 3+5+8

17. LaynaMae

1. 11 2. 16 3. 4 4. 16

18. amistre64

good, now the simplifications give us: 1. x^11/4 2. x^16/4 3. x^4 4. x^16 /4 i assume the problem is to find the one that is not correct?

19. LaynaMae

No, the problem is: Using complete sentences, explain the steps in simplifying the expression of each student and identify who is correct.

20. amistre64

using the properties of exponents .... we simplify these results to what we got Joe is bad, the rest are fine

21. LaynaMae

"We simplify these results to what we got" ... what does that mean ?

22. amistre64

well, the others presented the oroperties, i thought i helped you organize them and we simplified them to the stuff the we posted .... its up to you to present it in a suitable fashion.

23. LaynaMae

I'm not good at this , that's why I posted it here . For guidance . I appreciate what I have gotten , though .

24. amistre64

i wish i could stay, but my office is closing up til tomorrow. good luck :)

25. LaynaMae

Thank you

I wrote down what I think you mean by complete sentences...I hope it helps! :) Oh, attached should be a picture of my work/explanation.

27. LaynaMae

Thank you so much !
