Question

What is the square root of 12 the power of 2 + 5 the power of 2?

Answer 1

37

Explanation:

I'm assuming you meant
`(sqrt12)^2 + 5^2`

Well then, that's easy.
The square of a square-root is what's inside the root.
You'll have to remember the rule:
`(sqrt(a))^2=a` (where `a >= 0`, i.e. only positive numbers)
(Note: this is different from the square-root of a square
i.e. `sqrt(a^2) = abs(a)` where `abs(a)` is the absolute value of a, for all a, not only positive numbers.)

So, we have:
`12+5*5=12+25=37`
