Question

Convert the following products into factorials.: $2\times 4\times 6\times 8$

Answer 1

Given ,

$2\times 4\times 6\times 8\Rightarrow (2\times 1)\times (2\times 2)\times (2\times 3)\times (2\times 4)\Rightarrow \left(2{)}^4\right(1\times 2\times 3\times 4)\Rightarrow (2{)}^4(4!)$

Hence the correct value of above expression is $\left(2{)}^4\right(4!)$
