Step-by-step explanation:

The square root of a number is the number that, when multiplied by itself, gives the original number.

For example, the square root of 9 is 3, as 3 x 3 = 9.

The square root of 25 is 5, as 5 x 5 = 25.

The square root of 49 is 7, as 7 x 7 = 49.

The square root can be positive or negative (-3 x -3 equals 9, -5 x -5 = 25, and -7 x -7 = 49). When people say “square root,” they usually refer to the positive square root.

Answer 2

$\sqrt{15} \times \sqrt{45} \\ \\ = \sqrt{15 \times 45} \\ \\ = \sqrt{3 \times 5 \times 3 \times 3 \times 5} \\ \\ = \sqrt{ {3}^{2} \times {5}^{2} \times 3 } \\ \\ = 3 \times 5 \sqrt{3} \\ \\ = 15 \sqrt{3}$
