Question

multiplicative inverse of 2/3-³

Answer 1

multiplicative inverse : if any number X is given we have to find out multiplicative inverse then, just find 1/X . 1/X is not other than multiplicative inverse of X.
in simple way you can say that if the product of two different numbers equals 1 then, one is multiplicative inverse of other.


we have to find out multiplicative inverse of $\frac{2}{3^{-3}}$

Let $\mathbf{X}=\frac{2}{3^{-3}}$

then, multiplicative inverse of X is 1/X,

so, 1/X = $\frac{1}{\frac{2}{3^{-3}}}$

= $\frac{3^{-3}}{2}$

= $\frac{1}{54}$
