Question

17. Evaluate each pair of expressions.a. (-3) to the -8th power and -3 to the -8th power

Answer 1

17. Evaluate each pair of expressions.

a. (-3) to the -8th power and -3 to the -8th power

(-3) to the -8th power

the above is the same as:

`\mleft(-3\mright)^(-8)=(1)/(\left(-3\right)^8)=(1)/(6561)`

-3 to the -8th power

in this case, the above is:

`-3^(-8)=-(1)/(3^8)=-(1)/(6561)`
