    Vx + V9 = 19

    Vx + 3 = 19

    Vx = 19 - 3

    Vx = 16 elevando os dois membros da equação ao quadrado

    x = 256

    √x+√9=19 >>>
    √x +3=19 >>>
    √x=19 - 3 >>>
    √x=16 >>>
    (√x)²=(16)² >>> Elevamos os dois mebros ao quadrado para tira a √
    x=256 >>>

    Verificando

    √x+√9=19
    como x = 256, teremos

    √x+√9=19
    √256+√9=19
    16+3=19
    19=19 >>>(v)

    x = 256

    raiz quadrada (x) + raiz quadrada (9) = 19

    raiz quadrada (x) + 3 = 19

    raiz quadrada (x) = 16

    16 ao quadrado = 256

    raiz quadrada (256) = 16

    16 + 3 = 19
