Answer:

It is irrational and equal to 5 times the square root of 2.

Explanation:

The statement that is true about the expression:

( √(32) ) + √2

( √(16 * 2) ) + √2

( √(4²) *√2 ) + √2

( 4 *√2 ) + √2

( √2+√2+√2+√2 ) + √2

...and this is ( 4 ) + 1 times √2

The answer is 5 times √2

So the expression is irrational and equal to 5 times the square root of 2.
