What is the sum and classification of Two-fifths + StartRoot 88 EndRoot?

“A. 9.78083151..., irrational.

Step-by-step explanation:

We are asked to find the sum and classification of \frac{2}{5}+\sqrt{88}

5

2

+

88

.

Since 88 is not a perfect square, so we will find the value of square root of 88 using a calculator.

\frac{2}{5}+9.3808315196468591

5

2

+9.3808315196468591

Upon adding both numbers we will get,

9.78083151964685919.7808315196468591

Since 2/5 is a rational number and \sqrt{88}

88

is an irrational number as its decimal values are not terminating, therefore, the sum of both numbers will result in an irrational numbers”
