Question

$\sqrt{80} + \sqrt[3]{245} - \sqrt{152}$
​

Answer 1

Step-by-step explanation:

In mathematics, a square root of a number x is a number r such that r2 = x.

For example:

1. The square root of 25 is 5 because 52 = 25.

3. The square root of 2 is 1.41421356237 approximately.

3. The square root of pi (π) is 1.77245385102 approximately.

Answer 2

Answer:

$\sqrt{80} + 3 \sqrt{245} - \sqrt{125}$

$= \sqrt{4 \times 4 \times 5} + 3 \sqrt{7 \times 7 \times 5} - \sqrt{5 \times 5 \times 5}$

$= 4 \sqrt{5} + 3 \times 7 \sqrt{5} - 5 \sqrt{5}$

$= 4 \sqrt{5} + 21 \sqrt{5} - 5 \sqrt{5}$

$= 20 \sqrt{5}$
