The value of 3 power of -2

1.	The value of 3 power of -2
Answer» We have to FIND the VALUE of :- $\large({3}) \bf^{ - 2}$ We KNOW that :- $\boxed{\large({a}) \bf^{ - n} = \dfrac{1}{ {a}^{n} } }$ $\implies\sf({3}) ^{ - 2} = \dfrac{1}{ {3}^{2} }$ $\implies\sf \dfrac{1}{ {3} } \times \dfrac{1}{ {3} }$ $\implies\sf \dfrac{1}{ {9} }$ ANSWER : $\large({3}) \bf^{ - 2} = \dfrac{1}{9}$ ____________________ LEARN more : $\sf1)a^m\times a^n= {a}^{(m + n)}$ $\sf2) {( {a}^{m})}^{n} = {a}^{mn}$ $\sf3) {ab}^{n} = {a}^{n} {b}^{n}$ $\sf4) \frac{ {(a)}^{m} }{ {(a)}^{n} } = {a}^{m - n}$ $\sf5) {a}^{ - b} = \frac{1}{ {a}^{b} }$
