sqrt(a^2)=17

a^{2} = 17

a = 17, a = - 17

Solution steps

a^{2} = 17

Square both sides:

a^{2} = 289

a^{2} = 289

Solve

a^{2} = 289 : a = 17, a = - 17

a = 17, a = - 17

Verify Solutions:

a = 17

True

, a = - 17

True

The solutions are

a = 17, a = - 17

5 x - 19 - 5 x = - 1

1 - x^{2} = x

x^{2} + 5 = x + 3

(6 x - 3)^{\frac{2}{3}} + 6 = 15

x^{\frac{4}{3}} = 81
