skullpatrol · Answer

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

ranga · Answer

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

skullpatrol · Answer

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

anonymous · Answer

amistre64 · Answer

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

anonymous · Answer

Very ..

amistre64 · Answer

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?

amistre64 · Answer

second one i mistyped:

3+5+8

anonymous · Answer

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

amistre64 · Answer

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?

anonymous · Answer

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

amistre64 · Answer

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

anonymous · Answer

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

amistre64 · Answer

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.
