Answer 2

Answer:

$1 \frac{7}{20}$  Please mark me as brainliest.

Step-by-step explanation:

First we will simplify, then we will find reciprocal.

$= (\frac{3}{2})^{-2} + (\frac{2}{3})^3\\= (\frac{2}{3})^{2} + (\frac{2}{3})^3\\= \frac{4}{9} + \frac{8}{27}\\= \frac{12+8}{27}\\= \frac{20}{27}$

Reciprocal:

$\frac{27}{20}\\= 1 \frac{7}{20}$
