GPT 3.5
To find the value of y^-2 z^2 for y=-3 and z=-5, we substitute these values into the expression.
y^-2 z^2 = (-3)^-2 (-5)^2
First, we evaluate (-3)^-2.
(-3)^-2 = 1/(-3)^2 = 1/9
Next, we evaluate (-5)^2.
(-5)^2 = 25
Now, we substitute these values back into the expression.
y^-2 z^2 = (1/9)(25)
We can simplify the expression further by multiplying 1/9 and 25:
(1/9)(25) = 25/9
Therefore, the value of y^-2 z^2 for y=-3 and z=-5 is 25/9.
y^-2 z^2 = (-3)^-2 (-5)^2
First, we evaluate (-3)^-2.
(-3)^-2 = 1/(-3)^2 = 1/9
Next, we evaluate (-5)^2.
(-5)^2 = 25
Now, we substitute these values back into the expression.
y^-2 z^2 = (1/9)(25)
We can simplify the expression further by multiplying 1/9 and 25:
(1/9)(25) = 25/9
Therefore, the value of y^-2 z^2 for y=-3 and z=-5 is 25/9.
