Solution Steps

Step 1: Combine like terms

First, combine the terms with the same base. For the base q q , we have q4 q^{4} and q1 q^{-1} . For the base h h , we have h4 h^{-4} and h4 h^{4} .

q4h4h4q1=q4q1h4h4 q^{4} h^{-4} h^{4} q^{-1} = q^{4} q^{-1} h^{-4} h^{4}

Step 2: Apply the laws of exponents

Use the laws of exponents to simplify the expression. Specifically, aman=am+n a^{m} \cdot a^{n} = a^{m+n} .

q4q1=q4+(1)=q3 q^{4} q^{-1} = q^{4 + (-1)} = q^{3} h4h4=h4+4=h0 h^{-4} h^{4} = h^{-4 + 4} = h^{0}

Step 3: Simplify h0 h^{0}

Any non-zero number raised to the power of 0 is 1. Therefore:

h0=1 h^{0} = 1

Step 4: Combine the results

Now, combine the simplified terms:

q31=q3 q^{3} \cdot 1 = q^{3}

Final Answer

The simplified expression with only positive exponents is:

q3 \boxed{q^{3}}
