Q. Simplify. Assume all variables are positive.\newlineb65×b75b^{\frac{6}{5}} \times b^{\frac{7}{5}}\newlineWrite your answer in the form AA or AB\frac{A}{B}, where AA and BB are constants or variable expressions that have no variables in common. All exponents in your answer should be positive.\newline______
  1. Multiply powers with same base: When multiplying powers with the same base, we add the exponents. So we add the exponents 65\frac{6}{5} and 75\frac{7}{5}. \newlineb65×b75=b(65+75)b^{\frac{6}{5}} \times b^{\frac{7}{5}} = b^{\left(\frac{6}{5} + \frac{7}{5}\right)}
  2. Calculate sum of exponents: Calculate the sum of the exponents.\newline(65)+(75)=(6+75)=135(\frac{6}{5}) + (\frac{7}{5}) = (\frac{6 + 7}{5}) = \frac{13}{5}
  3. Write result as single power: Write the result as a single power of bb.b65×b75=b135b^{\frac{6}{5}} \times b^{\frac{7}{5}} = b^{\frac{13}{5}}
