Question

Please help me, thank you

Answer 1

• 7^0 = 1

• 4^-2 = 0.0625

Step-by-step explanation(A):

`a^(-b)=(1)/(a^b)\\(1)/(4^2)\\4^2=16\\(1)/(16)\\= 0.0625`

Step-by-step explanation(BA):

`7 / 7 = 1`

when dealing with an exponent of 0, your answer essentially is always 1, so divide the number by itself.

Step-by-step explanation(BB):

`a^0=1,\: \:a\\e \:0`

Answer 2

The first one is 1 the second one is 1/16 = 0.0625
