## Related Questions x squared means x times x. Since x can be any number, x times x can also be any number. x times x equals x^2, or x squared. x2 is an expression that can be read "x squared" or "x to the power of two". It is equal to x times x. A number is x squared plus forty four is equal to the number x to the fourth power times three?   No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)   x to the power of 2 is equal to x times x (x squared). This is written as x2. If x is equal to 5, then x squared plus 25 is equal to 50. 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. 36 squared times 24 squared is equal to 746,496.    do you mean (x2)(x2)(x)(x) would equal x6 13 squared x 4 squared is equal to 2,704. 144 squared x 36 squared is equal to 26,873,856. No. Cos squared x is not the same as cos x squared. Cos squared x means cos (x) times cos (x) Cos x squared means cos (x squared) (watts equal) voltage times current (e x I ) 120 x 20 resistance times current squared (r x I squared) 6 ohms x20 squared voltage squared divided by resistance (E squared divided by resistance) 120squared divided by 6 check OHMS LAW, 2 x cosine squared x -1 which also equals cos (2x) 289 squared times 289 squared is equal to 6,975,757,441.  We can't be sure from a reading of the question.The question could be saying " ... five times [ (a number X) squared ] ...",or it could be saying " ... (five times a number X) squared ...' .In the first case, it's [ 5x2 ] .In the second case, it's [ (5x)2 ] which is equal to [ 25 x2 ].
