Question

Find the value of √75 × √243​

Answer 1

Answer:

Its answer is 135.

Answer 2

Step-by-step explanation:

$= \sqrt{5 \times 5 \times 3} \times \sqrt{3 \times 3 \times 3 \times 3 \times 3}$

$\sqrt{x} \times \sqrt{y } = \sqrt{x \times y} \\ therefore \: \\ \sqrt{5 \times 5 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 } \\ = 5 \times3 \times 3 \times 3 = 135$
