3 separate problems

3. anonymous

oh so what have you done so far? what part are you lost?

4. anonymous

i seems like all are either -1/-49 or -49.

5. anonymous

hmm ok for number 1 when you have anything like this $A ^{-b}$ = $\frac{1}{A^b}$ so for the first do that and it should be easy to solve it

6. anonymous

for the second the - sign is outside the 7 so you scared 7 first and then multiply it with the - sign

7. anonymous

for the third its simply (-7) *(-7)

a. = $\frac{1}{49}$ b. = $-49$ c. = 49
