Rewrite the innermost expressions with negative exponents:

\displaystyle \left[\left(\frac{a^6}{5b^{-1}}\right)^2 \cdot \left(\frac{b}{9a^{-11}}\right)^{-1}\right]^{-3}

\displaystyle \implies \left[\left(\frac{a^6b^1}{5}\right)^2 \cdot \left(\frac{ba^{11}}{9}\right)^{-1}\right]^{-3}

\displaystyle \implies \left[\left(\frac{a^6b^1}{5}\right)^2 \cdot \left(\frac9{ba^{11}}\right)^1\right]^{-3}

Simplify the product:

\displaystyle \implies \left[\left(\frac{a^6b}{5}\right)^2 \cdot \frac9{ba^{11}}\right]^{-3}

\displaystyle \implies \left[\frac{\left(a^6b\right)^2}{5^2} \cdot \frac9{ba^{11}}\right]^{-3}

\displaystyle \implies \left[\frac{\left(a^6\right)^2b^2}{25} \cdot \frac9{ba^{11}}\right]^{-3}

\displaystyle \implies \left[\frac{a^{12}b^2}{25} \cdot \frac9{ba^{11}}\right]^{-3}

\displaystyle \implies \left[\frac{9ab}{25}\right]^{-3}

Rewrite the last negative exponent:

\implies \boxed{\left(\frac{25}{9ab}\right)^3}

Josephine can correct her students' test papers in 9 hours, but if her teacher's assistant helps, it would take them 7 hours. Ho
kirill [66]

Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given as follows:

  • Josephine: 1/9.
  • Assistant: 1/x.
  • Together: 1/7.

Hence:

\frac{1}{9} + \frac{1}{x} = \frac{1}{7}

\frac{x + 9}{9x} = \frac{1}{7}

9x = 7x + 63

2x = 63

x = 31.5.

It would take the assistant 31 hours and 30 minutes to do it alone.
