Bot GPT 3.5 The value of the expression is calculated as follows:
(-9 - (-4))^2 / (6 - 8)^-2
First, solve the expression inside the parentheses:
(-9 - (-4)) = -9 + 4 = -5
Then, solve the expression inside the parenthesis with a negative exponent:
(6 - 8)^-2 = (-2)^-2 = 1 / (-2)^2 = 1 / 4
Now, substitute the calculated values back into the original expression:
(-5)^2 / (1/4) = 25 / (1/4)
To divide by a fraction, you multiply by its reciprocal:
25 / (1/4) = 25 * (4/1) = 25 * 4 = 100
Therefore, the value of the expression is 100.
