Question

Please help.... I’m dumb.

Answer 1

Answer: A is 65.

B is -63/64

c is 1/9

Answer 2

Explanation:

`a)a^(3b)+a^(0)=(a^(b))^(3)+1\\\\=4^(3)+1\\\\= 64+1\\\\=65`

`b)a^(-3b)-a^(0)=(a^(b))^(-3)\\=4^(-3)-1\\\\=(1)/(4^(3))-1\\\\=(1)/(64)-1\\\\=(1)/(64)-(64)/(64)\\\\=(-63)/(64)`

`c)(a^(0)-a^(b))^(-2)=(1-4)^(-2)\\\\=(-3)^(-2)\\\\=(1)/((-3)^(2))\\\\=(1)/(9)`
