The answer to the above math expression is . See the computation below.

<h3>What is the calculation justifying the above?</h3>

First we solve for the numerator. The numerator is:

7√2 - 2√16

Where:

7√2 = 9.89949493661; and

2√16 = 8

Hence,

7√2 - 2√16 = 1.89949493661

Next we solve for the denominator. This is given as:

3√8=8.48528137424

Hence,

(7√2 - 2√16)/3√8 = 1.89949493661/8.48528137424

= 0.22385762508

$\approx$ 0.224
