Question

What is this expression in simplified form?
2√2x7√18

Answer 1

Answer=84

Explanation:

Greetings !

Given expression

`2 √(2) * 7 √(18)`

Apply radical rule

`√(a) √(b) = √(ab)`

where

`a \geqslant 0,b \geqslant 0`

Thus

`√(2) √(18) = √(2 * 18)`

Multiply the numbers 2.18=36

`√(36)`

`= 2 √(36) * 7 \\ √(36) = 6`

simplify

`2 * 6 * 7 =84`

Hope it helps!
