Simplify: $$\left( 1.5 + \frac{3}{8} \right)^{3} - \left( \frac{9}{5} \times 1.25 \right)$$​

Correct option is A

Given:

​$$\left( 1.5 + \frac{3}{8} \right)^{3} - \left( \frac{9}{5} \times 1.25 \right)$$

Solution:

​$$\left( 1.5 + 0.375 \right)^{3} - \left( 1.8\times 1.25 \right)$$

=$$\left( 1.875 \right)^{3} - 2.25$$ 

= 6.5918 - 2.25 

= 4.3418
