Think about it: If you multiply them together, you get (3 X 3 X 3 X 3)(3 X 3 X 3 X 3 X 3 X 3), which means there are ten 3s multiplied together, or 3^10. When exponents that share the same base are multiplied, the exponents are added. If there are four qâs in the numerator (q X q X q X q) and two in the denominator (q X q), two of the qâs will cancel each other out, leaving only two qâs in the numerator. = 10. The skills you will gain from this module will help you in simplifying polynomials. This would leave you with the answer x^6. Step 5: Apply the Quotient Rule. In other words, if you wanted to raise 2/5 to the third power, you would have to raise the 2 and the 5 to the third power, so your answer would be (2^3)/(5^3) or 8/125. 31/10/2020 16/11/2020 By Math Original No comments .
