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

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
