Answer:
Step-by-step explanation:
First, let's examine our original statement.
Using exponent rules, we know that if we have , then simplified, the answer will be equivalent to
.
So we can simplify this by adding the exponents and
.
Converting into fourths gets us
.
.
So we now have .
When we have a number to a fraction power, it's the same thing as taking the denominator root of the base to the numerator power.
Basically, this becomes
. (The numerator is what we raise x to the power of, the denominator is the root we take of that).
