Definition â€” Rational Exponent With Numerator m
If a is a real number, m is a nonnegative integer, n is a positive integer, and is in lowest terms, then
If n is even, then am/n is a real number only when a ≥ 0.
When m = 1, we have
Rewrite using a radical and evaluate: 323/5
We will use three different methods to solve this problem.
In summary, all three methods lead to the same result: 323/5 = 8
Method 2 typically means dealing with larger numbers since we first evaluate the power.
