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.
It is equal to -2.
only when x is equal to 2
I assume you mean (x+10)(x+2) This would equal x^2+12x+20 x^2 means x squared
No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
that depends on what that expression is equal to. If you are asking what x equals if "-x-2 = 0" for example, then the solution would be: -x-2 = 0 -x = 2 add 2 to both sides x = -2 multiply both sides by negative 1 - solved If, however, -x-2 does NOT equal zero, then this solution is incorrect. -x - 2 equal to zero, because you found that the value of x is a negative number, x = -2, and the opposite of x is a positive number, -x = -(-2) = 2. Thus -x - 2 = -(-2) - 2 = 2 - 2 = 0 If this is not a maths question, then SE made it X-2 instead of XI because X-2 was a continuation of X, instead a new universe like they usually have when they change the Roman numeral.
2 x 2 x 2 x 2 x 2 x 2
2 x 4 x 8 x 10 is equal to 640.
2 x 3 x 5 is equal to 30.
2 x 7 x 7 is equal to 98.
If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.
If x^2 = 0, x = 0 Only 0^2 can equal 0.
