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

tangent
