Question

What number multiplied by itself 2 times equals 49

Answer 1

Explanation:

You want the square root of 49, which is 7

Answer 2

You're basically looking for the square root of 49. In fact, if a number
`x` gives
`y` when multiplied by itself two times, then you have
`x^2 = y`, which also means that
`x` is the square root of
`y`, i.e.
`x = √(y)`

In your case, the answer is 7, because you have

`√(49)=7 \iff 7^2 = 49`

which is indeed true
