Hi there!
A recipe for cake needs 3/4 of a cup of milk.
We are making 1/2 of the recipe, which means we also need half of the milk needed for the total recipe. Therefore, we can multiply 1/2 (half of the recipe) by 3/4 (the total amount of cups of milk needed for the total recipe).

Hence, we need
3/8 cups of milk
X to the power of 8
When dividing powers, you subtract the "small numbers". When multiplying, you add them. 3-(-5) = 8
Hope it helps!
