Question

How do you solve `sqrtv = 2`?

Answer 1

`v = 4`

Explanation:

Take a look at what you have here

`sqrt(v) = 2`

You take the square root from an unknown number `v` and get an integer as the result. This automatically means that the number under the square root is a perfect square.

You can solve for `v` by squaring both sides of the equation.

`(sqrt(v))^2 = 2^2`

`v = color(green)(4)`

This is the only solution to your equation, `x=4`, which is indeed a perfect square.
