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
3 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 |
