Question

What is the following product? sqr root 10 x sqr root 10

Answer 1

Answer:

10

Step-by-step explanation:

Note that $\sqrt{a}$ × $\sqrt{a}$ = a

Consider the following example

$\sqrt{100}$ × $\sqrt{100}$

= 10 × 10

= 100 ← the value inside the radical, thus

$\sqrt{10}$ × $\sqrt{10}$ = 10
