11^3.8=x^2

Solution for 11^3.8=x^2 equation:

11^3.8=x^2

We move all terms to the left:

11^3.8-(x^2)=0

We add all the numbers together, and all the variables

-1x^2+9063.42204273=0

a = -1; b = 0; c = +9063.42204273;
Δ = b2-4ac
Δ = 02-4·(-1)·9063.42204273
Δ = 36253.6881709
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{36253.6881709}}{2*-1}=\frac{0-\sqrt{36253.6881709}}{-2}
=-\frac{\sqrt{}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{36253.6881709}}{2*-1}=\frac{0+\sqrt{36253.6881709}}{-2}
=\frac{\sqrt{}}{-2}
