Finds the solutions to x^2=20

Answers

Solution of an equationx^(2) =20 is x= \pm 2√(5).

What is solution of an equation?

The solution of an equation is the array of all values that, when replaced for unknowns, make an equation true.

Given

x^(2) =20

x=√(20)

x=√(4 * 5 )

x=\sqrt{2^(2)  * 5}

x= \pm 2√(5)

Solution of an equationx^(2) =20 is x= \pm 2√(5).
