Answer 2

b. If square root of 5 =2.236 then the value of √5/2-10√5+√125 is equal to -10.062.

Given,

$\sqrt{5} = 2.236$

To find,

$\frac{\sqrt{5} }{2} - 10\sqrt{5} + \sqrt{125}$

Solution,

substituting the value $\sqrt{5} = 2.236$ in the given equation

$\frac{\sqrt{5} }{2} - 10\sqrt{5} + \sqrt{125}\\\\\frac{2.236}{2} - 10(2.236) + 5\sqrt{5}\\ \\\frac{2.236}{2} - 10(2.236) + 5(2.236)\\\\1.118 - 22.36 + 11.18\\\\-10.062$

Therefore, if square root of 5 =2.236 then the value of $\frac{\sqrt{5} }{2} - 10\sqrt{5} + \sqrt{125}$ is equal to -10.062.
