Simplify the expression. Assume that all variables are positive. Exponents in simplified form should all be
positive.

Given:

The given expression is

We need to determine the exponents in simplified form.

Exponents in simplified form:

Let us determine the exponent in simplified form.

Let us apply the exponent rule

Thus, we have;

Adding the fractions, we get;

Cancelling the common terms, we have;

Simplifying the exponent, we get;

Adding the exponent, we have;

Thus, the simplified form of the expression is

idk

step-by-step explanation: i just don't

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
