Square root 5 x square root 5 x square root 2 x square root 2 Answer left in surds

Harlamova29_29 [7]

Answer:

10 or $\sqrt{100}$ (in surds)

Step-by-step explanation:

$\sqrt{5}$ × $\sqrt{5}$ × $\sqrt{2}$ × $\sqrt{2}$ = 5×2 = 10 or $\sqrt{100}$

When the same square root multiply each other, they equal to the number in the square root. E.g. $\sqrt{5}$ × $\sqrt{5}$ = 5 because $\sqrt{5}$ × $\sqrt{5}$ also equals to $\sqrt{25}$ , which is 5.

Hope this is helpful :)
