What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
Ivahew [28]

For the exponential expression, 16^{1/4} the simplified value is 2.

<h3>How to simplify the exponential expression?</h3>

First, we need to remember a rule for exponential expressions, it says that:

x^{1/n} = \sqrt[n]{x}

Then we can rewrite the given exponential expression as:

16^{1/4} =\sqrt[4]{16}

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

16^{1/4} =\sqrt[4]{16} = 2

So the simplified value of the exponential expression is 2.
