Unclear what you're asking:

If x=7, then x^2 (that is, "x squared") equals 49.

or

If x^2=7, then x equals the Square root of 7, or about 2.64575

Seven squared = 7 x 7 = 49


2 x 2 x 2 x 7 x 7 is equal to 2 cubed times 7 squared. 2 cubed is equal to 8, and 7 squared is equal to 49. Therefore, 2 x 2 x 2 x 7 x 7 is equal to 8 x 49 = 392.


This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.


They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.


49 = (±7)2 x2<=49 => -7 <= x <= 7



Without an equality sign the expression given can't be considered to be an equation and therefore has no solution.


It does not equal anything.The inequality implies that x sqrt(7) where sqrt represents the principal square root.


If x is equal to 5, then x squared plus 25 is equal to 50.


Yes, x times x equals x squared.

Yes because 7 squared is equal to 49


No, not strictly speaking. Length squared would have the same units as area but is not equal to it. Length x width is area. If I have a rectangle that is 4m wide x 7m in length then the area would be 7x4 = 28 m2. But length squared would be 7 x 7 = 49m2 which is incorrect.


8 squared x 2 is equal to 128.


3 squared is 3 x 3 or 9.
