Evaluate 256 to the one-fourth
power.

256 to the one-fourth power is
taking the fourth root of 256. The fourth root of 256 is saying
what number to the fourth power, what number multiplied by itself four times, is
equal to 256. Here we’ll use a calculator. And I’ll actually enter 256, and
then for the exponent value I’ll put one over four. And that tells me that it equals
four. Four to the fourth power equals
256. And that means 256 to the
one-fourth power equals four.
