Answer 1

Answer:

Given number are

\mathbf{\frac{3^{4}}{3^{2}}}

3

2

3

4

Multiply by \mathbf{3^{-2}}3

−2

in numerator and denominator, we will get

\mathbf{\frac{3^{4}\times 3^{-2}}{3^{2}\times 3^{-2}}}

3

2

×3

−2

3

4

×3

−2

Exponent will add on multiplication if base is same.So we will get

\mathbf{\frac{3^{4-2}}{3^{2-2}}}

3

2−2

3

4−2

On solving exponent, we will get

\mathbf{\frac{3^{2}}{3^{0}}}

3

0

2

If a number have exponent zero, its value is equal to 1.So

\mathbf{\frac{3^{2}}{1}}

1

3

2

So

3² = 9
