Does 2 to the negative power of 2 equal negative 4?
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.
What does x equal when -x-2?
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.
What does a number over infinity equal?
0. This is the same as the limit of 1/x as x approaches infinity, which is is 0. This is because 1/1,000 = .001 and 1/1,000,000 = .000001 and 1/100,000,000,000 = .0000000001 etc.
Does 2x2x2x2x2 equal 36?
2 x 2 = 4 x 2 = 8 x 2 = 16 x 2 = 32
If x varies jointly as y and the square as z and x equal 40 when y equal 20 and z equal 2 find x when y equal 30 and z equal 3?
