to make the calculation easier factor the expression

Answer 1

$<b>$Answer :

$= > {3}^{20} + {3}^{21} + {3}^{22} + {3}^{23} \\ \\ = > {3}^{20} \: is \: common \: in \: every \: term \\ \\ = > so \: lets \: take \: it \: out. \\ \\ = > {3}^{20} \times 1 + {3}^{20} \times 3 + {3}^{20} \times 9 + {3}^{20} \times 27 \\ \\ = > {3}^{20} (1 + 3 + 9 + 27) \\ \\ = > {3}^{20} (40) \\ \\ = > {3}^{20} \times 40$

$\textbf{Hence, {3}^{20} \times 40 \: is \: your\: required \: answer. }$

Tysm for the question!
