Fractions as Exponents: 16 3/2

In summary, fractions as exponents are a mathematical expression where a fraction is used as the exponent. The expression "16 3/2" can be read as "16 to the power of three halves" or "the cube root of 16". The value of "16 3/2" can be calculated by converting the fraction exponent to a decimal and taking the root of the base. Using fractions as exponents allows for the calculation of roots, which is useful in mathematical and scientific applications. Fractions can be used as exponents for any positive number, but the resulting value may not always be a real number.

Here's a quicker way to check your answer. Go to Wolfram Alpha and type in your problem. It will simplify it for you and you can see if your answer matches.

You need to be careful though when entering the problem. For example, your problem should be written there as 16^[3/2]. The ^ symbol means exponent. If there's a fraction, put the fraction inside [] brackets.
