Question

Raíz cuadrada de X/9 +(4/9)=1/2

Answer 1

$\sqrt{ \frac{x}{9} } + \frac{4}{9} = \frac{1}{2}$   

$\sqrt{ \frac{x}{9} } = \frac{1}{2} - \frac{4}{9}$

$\sqrt{ \frac{x}{2} }= \frac{9-8}{18}$

$\sqrt{ \frac{x}{9} }= \frac{1}{18}$

$( \sqrt{ \frac{x}{9} } )^{2} = ( \frac{1}{18}) ^{2}$

$\frac{x}{9} = \frac{1}{324}$

$x = \frac{9}{324}$

$x = \frac{1}{36}$

Answer 2

Resolver.

√x/9  + 4/9 = 1/2
√x/9 = 1/2 - 4/9    El mcm de 2 y 9 es 18
√x/9 = 9/18 - 8/18
√x/9 = 1/18
√x/3 = 1/18
√x = 3/18
√x = 1/6    Eleva al cuadrado ambos lados de la ecuacion
(√x)² = (1/6)²
x = 1²/6²
x = 1/36

Respuesta
x = 1/36
