is -2^-2*(2^8) equivilant to -64
No, -2^-2*(2^8) is not equivalent to -64.
To solve the expression, we need to follow the order of operations (PEMDAS/BODMAS).
First, calculate the value of the exponent in the parentheses: 2^8 = 256.
Next, calculate the value of -2^-2:
-2^-2 = -1/(2^2) = -1/4.
Finally, multiply -1/4 by 256:
-1/4 * 256 = -64.
Therefore, -2^-2*(2^8) is equivalent to -64.
