Question

8 to power -2 multiplied by a to power of 7

Answer 1

(8^ -2)(4^4)(16^ -1)


a^-x=(1/a^x)


(4^4)/((8^2)(16))

"NOTE" 16^1=16


4^4=256

8^2=64

256/((64)(16))=1/4

convert 1/4 to a power of two

(4) is 2

1/4=1/(2^2)

1^2=1

(1/2)^2=(1/4)


1/2 to the power of 2 is the answer

It would look like this

1/2²
