Question

Help...giving 20 points (number 3 nothing else)

Answer 1

see below

Explanation:

`((7)/(2) )^(4) =(7^4)/(2^4)=(2401)/(16)`

`(7*2^3)^3=7^3*2^(3*3)=343*2^9=343*512=175616`

`(7^2)(7^2)=7^(2+2)=7^(4)=2401`

`(7^2)(7)^0=7^(2+0)=7^2=49`

`((7)/(2)) ^(-4)=(7^(-4))/(2^(-4))=(2^(4))/(7^4) =(16)/(2401)`

`(7^6)/(7^3) =7^(6-3)=7^(3)=343`

i don't know if you need all the numbers if you don't copy till when it has the exponents
