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.
8
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.
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.
(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
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.
The answer is 11 !
