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.
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.
2 x 2 = 4 x 2 = 8 x 2 = 16 x 2 = 32

2 plus 29 plus 6.8 plus 001 is equal to 38.8
1.001
001 has one significant digit, so the answer can only have one. 1.2 x 001 = 1
1 picogram = * 1 x 10-12 gram * 0.000 000 000 001 gram
One hundredth !
The standard notation for 6.256 x 10-001 = 0.6256
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.
001 equals 1 so it is just 1 * 10^0 (or 1e0 if you want). If you meant to type 0.01, then it would be 1 * 10^-2 (or 1e-2).
The decimal number .001 is equal to 1 over 1,000.
.001
It is equal to -2.
