Answer 2

Answer:

$\frac{16}{9} \\or 12\\or 1.7\\or 1.8$

Step-by-step explanation:

Step 1:

remove parentheses

${(-\frac{3}{4} )^{-2} }$

Step 2:

use Negative Power Rule: $x^{-a} = \frac{1}{x^{a} }$

${\frac{1}{(-\frac{3}{4})^{2} } }$

Step 3:

since the power of 2 is even, the result will be positive

$\frac{1}{(\frac{3}{4})^{2} }$

Step 4:

use Division Distributive Property: $(\frac{x}{y} )^{a} = \frac{x^{a} }{y^{a} }$

$\frac{1}{\frac{3^{2} }{4^{2} } }$

Step 5:

simplify $3^{2} to9$

$\frac{1}{\frac{9}{4^{2} } }$

Step 6:

simplify $4^{2} to 16$

$\frac{1}{\frac{9}{16} }$

Step 7:

invert and multiply

$\frac{16}{9}$×$1$

Step 8:

simplify

$\frac{16}{9}$
