2*24.5 = 49
x=-3 or x=5
3.45
Twice. a*a is a squared.
simply see what you can multiply twice to get the number under the square root sign.

Oh, dude, like, yes, 52 is not a square number. A square number is like when you can multiply a number by itself to get it, you know? Like 7 times 7 is 49, square number. But 52? Nah, no square root action happening there.
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
It's a square number. Square numbers have a factor pair that is the same number twice. When listed, that number occurs once.

Twice. a*a is a squared.
simply see what you can multiply twice to get the number under the square root sign.
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
The square root of 10 times the square root of 10 = 10
The answer is 11 !
