(1- 1/3)³.
give proper explanation and steps​

Answer 1

Given:

A expression (1-1/3)³.

To Find :

Its simified value.

Answer:

We have ,

=$\sf{(1-\frac{1}{3})^{3}}$

=$\sf{(1)^{3}-(\frac{1}{3})^{3}-3\times 1\times \frac{1}{3}(1-\frac{1}{3})}$

using

• (a-b)³=a³-b³-3ab(a-b)

=$\sf{1-\frac{1}{27}-1(1-\frac{1}{3})}$

=$\sf{1-\frac{1}{27}-1+\frac{1}{3}}$

=$\sf{\frac{1}{3}-\frac{1}{27}}$

=$\sf{\frac{27-3}{27}}$

=$\sf{\frac{24}{27}}$

=${\underline{\boxed{\red{\dfrac{8}{9}}}}}$
