Question

if x=0.75 then what is the value of expression (1+x+x^2)+x^3/(1-x)

Answer 1

Step-by-step explanation:

Substituting value of x in the given equation, we get,

$1 + 0.75 + {0.75}^{2} + \frac{ {0.75}^{3} }{1 - 0.75} \\ \\ = > 1.75 + 0.5625 + \frac{0.421875}{0.25}$

$= > 2.3125 + 1.6875 \\ \\ = > 4$
