f(x) = 2x²
f(x) = 136
→ 2x² = 136
→ x² = 68
→ x = ±√68
As the positive value is required, x = √68 ≈ 8.246
If x squared = 5 then x = sqrt(5) = 2.2361 (approx).
The number that equals 121 when squared is 11.
5.477225575 squared equals 30.
b = sqrt32 or 4 root 2
No, it equals -2xy. lrn2math
it equals positive one. one squared is always one. if they're both negative, negative times negative is always positive.
A negative number squared equals a positive number. When multiplying, odd numbers of negatives result in a negative answer, and even numbers of negatives result in a positive answer.
If x squared = 5 then x = sqrt(5) = 2.2361 (approx).
Oh, dude, when you square a negative number, it becomes positive, so -6 squared is 36. It's like math trying to play tricks on you, but nah, we got this. So yeah, -6 squared equals 36, simple as that.

Those numbers would be 13 and 8. 13 squared + 8 squared This is equal to: 169 + 64 which equals 233 And finally, 13 - 8 equals 5.
66 squared equals 4,356.
