could someone help me with math?

Question

Simplify this expression. If the answer contains exponents, all exponents should be positive.

(h^5)^−3/h^-12

Answer 1

A negative exponent means that the variable should move to the opposite side of the fraction bar.  In you example (h⁵)^-3 should move to the denominator.  When you move it the -3 becomes +3.  The same is true for the h^-12 but in reverse.

 

Once you make you changes it will look like this h¹²/(h⁵)³

 

When an exponent is raised to a certain power you should multiply the exponents.  In this case (h⁵) is being raised to the 3rd power so you should multiply 5 and 3 and put the (h) to that power.

 

Then reduce by subtracting the exponents.
