I need answer

Dear Student ,

\frac{2.3 \times 2.3 \times 2.3 - 1}{2.3 \times 2.3 + 2.3 + 1} [u \sin g a^{3} - b^{3} = (a - b) (a^{2} + a b + b^{2})] = \frac{{(2.3)}^{3} - {(1)}^{3}}{{(2.3)}^{2} + 2.3 \times 1 + {(1)}^{2}} = \frac{(2.3 - 1) [{(2.3)}^{2} + 2.3 \times 1 + {(1)}^{2}]}{[{(2.3)}^{2} + 2.3 \times 1 + {(1)}^{2}]} = (2.3 - 1) = 1.3
