Question

what is the simplest form of root 40

Answer 1

The simple form of root 40 is 2 root10

Answer 2

When we have a composite number under square root then we split it into a group of prime numbers whose product is exactly the number and then we take out pairs and leave the single number inside the root.

Here, 40 = 2 * 2 * 2 * 5

$\bold{\sqrt{40}}$ = $\bold{\sqrt{2*2*2*5}}$ = $\bold{2\sqrt{2*5}}$ = $\bolld{2\sqrt{10}}$
