The mathematical expression of the given above is 4/y^-3 where only the denominator is raised to exponent -3. Remember that the expression x^-n may also be expressed as 1/x^n. Thus, for the given, transfer the y^-3 of the denominator to the numerator to give the final answer of 4y³.

The answer is 28m. You’re welcome; Brainliest would be appreciated though :)
The answer to your question is 3 to the 3rd power and 5 to the 2nd power. The reason why that's your answer is because there are three 3s so instead of doing 3*3*3 you can just simply do 3 to the 3rd power and do the same thing to the 5. You can see that there are two fives so you do 5 to the 2nd power.
Hope this helps:)
