What is the value if x = 2 ?

Hallo Guest!

$If\ x=2\ then$

$\dfrac{x^1\cdot x^2\cdot x^3\cdots x^{10}}{x^2\cdot x^4 \cdot x^6 \cdots x^{20}} = \dfrac{1}{x^{11+11+11+11+11}}=\dfrac{1}{2^{55}}=\color{blue}\dfrac{1}{36028797018963968}$

$\color{blue}=2.775 557 561 562 891 351 059 079 170 227 050 781 25\times 10^{-17}$
