$=\frac{a_{0}}{1}+\frac{a_{1}}{2}+\ldots .+\frac{a_{41}}{42}$

Vedclass · Accepted Answer

$\left( {\frac{{{3^{21}} - 1}}{{21}}} \right)$

Vedclass · Answer

$\int\limits_0^1 {{{\left( {1 + x + {x^2}} \right)}^{20}}} (2x + 1)dx$

$=\frac{a_{0}}{1}+\frac{a_{1}}{2}+\ldots .+\frac{a_{41}}{42}$

જો ${\left( {1 + x + {x^2}} \right)^{20}}\left( {2x + 1} \right) = {a_0} + {a_1}{x^1} + {a_2}{x^2} + ... + {a_{41}}{x^{41}}$ , હોય તો $\frac{{{a_0}}}{1} + \frac{{{a_1}}}{2} + .... + \frac{{{a_{41}}}}{{42}}$ ની કિમત મેળવો
