Answer:

- 4

Step-by-step explanation:

Using the rule of exponents

• a^{m} × a^{n} ⇔ a^{(m+n)}

• a^{-m} ⇔ \frac{1}{a^{m} }

(\frac{1}{9}) ^{a+1} = 9^{-(a+1)} = 3^{-2(a+1)}

and right side

= 3^{4(a+1)} × 3^{3(2-a)}

Hence

3^{-2a-2} = 3^{4a+4} × 3^{6-3a}

3^{-2a-2} = 3^{a+10}

Equating exponents on both sides gives

a + 10 = - 2a - 2 ( add 2a to both sides )

3a + 10 = - 2 (subtract 10 from both sides )

3a = - 12 ( divide both sides by 3 )

a = - 4
