Have you considered "10"?

anonymous · Answer

can you show how you solved this to get this answer please

tkhunny · Answer

It's an eyeball problem.  You should know the perfect squares.

$6^{2} = 36$

$7^{2} = 49$

$8^{2} = 64$

$9^{2} = 81$

$10^{2} = 100$

I'm new to solving equations like this, I was just trying to see how to solve the equation. It seems easy but hard to do

tkhunny · Answer

First, it's an expression, not an equation.  That is an important distinction.

Second, finding a square root can be a little tedious.  As you appear to be rather new at it, your best current bet might be what is known as "Guess and Check".  Given a little familiarity, like the short list I gave above, youcan make better guesses?

Example:  $\sqrt{75} = ??$

Well, we know $8^{2} = 64$  and $9^{2} =81$ , so $\sqrt{75}$ must be between 8 and 9.

Oh ok thanks a lot. That really does help. So the square is normally always 2?
