 Question from Zoey: What is the exponential form of 1/8?? Thxs

Hi Zoey,

Exponential form means anything involving exponents, so there are many answers to this question. I do know that $8 = 2^3$ so you could write

$\frac18 = \frac{1}{2^3}.$

You could also write

$\frac18 = \left( {\frac12} \right) ^3$

or

$\frac18 = 2^{-3}.$

I would say all of these are in exponential form but I am not sure what your teacher expects.
