-5 times the power of two

do you mean (-5)^2 ?

if so, then
= 25

think of it as (-5)(-5)

(5^-1+7^0)×5^3

To find -5 times the power of two, we first need to calculate the value of the power of two and then multiply it by -5.

The power of two refers to raising the number 2 to a certain exponent. In this case, the exponent is missing from the question. Assuming you want to know the value of -5 times 2 raised to the power of 2, we can proceed with the calculation.

To calculate 2 raised to the power of 2, we multiply 2 by itself: 2 × 2 = 4.

Now, to find -5 times 4, we simply multiply -5 by 4: -5 × 4 = -20.

Thus, -5 times the power of two (2 raised to the power of 2) equals -20.
