Answer:

The value of ((3)⁻⁵ ÷(3)⁻⁷) ÷ (3)⁻² = 81

Step-by-step explanation:

Given that((3)⁻⁵ ÷(3)⁻⁷) ÷ (3)⁻²

We have to solve the expression

((3)⁻⁵ ÷(3)⁻⁷) ÷ (3)⁻²

We know that \frac{a^{m} }{a^{n} }  = a^{m-n}

first we find the value of ((3)⁻⁵ ÷(3)⁻⁷)

\frac{3^{-5} }{3^{-7} } =3^{-5+7} =3^{2} =9

Now ((3)⁻⁵ ÷(3)⁻⁷) ÷ (3)⁻²

(3)²÷(3)⁻² = \frac{3^{2} }{3^{-2} } =3^{2+2} =3^{4} =81.

3⁴ = 3×3×3×3 = 81

Therefore, ((3)⁻⁵ ÷(3)⁻⁷) ÷ (3)⁻² = 81
