Calculate the value of 2^(–3) as a fraction in its simplest form.

To calculate the value of 2-3 first we know that a negative exponent is equivalent to the inverse of the same number with a positive exponent. 

Therefore 2-3= 1/23, the next step is to calculate 23, 222 = 8, so the answer in it's simplest form is 1/8
