Correct Answer - Option 1 :

\(\left(\frac{3}{2} \right)^5\)
**Concept:**

We know that

Dividend ÷ Divisor = Quotient

**Given:**

Dividend = \(\frac{2^{-6}}{3}\)

Quotient = \(\frac{3^{-6}}{2}\)

**Calculation:**

The required number, Divisor = Dividend ÷ Quotient

⇒ \(\rm Divisor = \frac{{\frac{{{2^{ - 6}}}}{3}}}{{\frac{{{3^{ - 6}}}}{2}}}\)

⇒ \(Divisor = \frac{{{2^{ - 5}}}}{{{3^{ - 5}}}} = {\left( {\frac{3}{2}} \right)^5}\)
