5=sqrt(a^2+3^2)

5 = a^{2} + 3^{2}

a = 4, a = - 4

Solution steps

5 = a^{2} + 3^{2}

Square both sides:

25 = a^{2} + 9

25 = a^{2} + 9

Solve

25 = a^{2} + 9 : a = 4, a = - 4

a = 4, a = - 4

Verify Solutions:

a = 4

True

, a = - 4

True

The solutions are

a = 4, a = - 4

x^{2} - 5 x + 1 - 1 - 8 x = 0

6 + 3 y - 4 = 9

x - 2 - 1 = 3 - x

3 3 x + 4 - x = 5 + x

6 + \frac{6}{x ^{\frac{5}{11}}} = 0
