How do you find a reciprocal of a number with an exponent?

Answer 1

'2' the number .

Its reciprocal is '1/2'.

or 1/2 , its reciprocal is '2.

however if an exponential is present

Then

2^(2) = 4 its reci[procal is 1/4 = 1/2^(2) = 2^(-2)

Conversely the reciprocal of 2^(-2) is 2^(2).

Answer 2

You change the sign of the exponent. For example, the reciprocal of 2 to the power 8 is 2 to the power -8. Alternately, you can change the whole expression to the denominator. In this case, the reciprocal of 2 to the power 8 is 1 divided by (2 to the power 8).
