Question

√x+1=7
a)
(Fazer verificação ) me ajudem pfvr

Answer 1

❑ Oie td bom?!

❑ Vamos resolver ok?!

→ $\sqrt{x+1} = 7$

→ $(\sqrt{x+1})^2= 7^2$

→ $x+1 = 49$

→ $x = 49-1$

→ $x = 48$

→ Verificando:

→ √48+1 = 7

→ √49 = 7

Answer 2

Oie, Td Bom?!

$\sqrt{x + 1} = 7$

$\sqrt{x + 1} {}^{2} = 7 {}^{2}$

$x + 1 = 49$

$x = 49 - 1$

$x = 48$

• Verificando:

$\sqrt{48 + 1} = 7$

$\sqrt{49} = 7$

$\sqrt{7 {}^{2} } = 7$

$7 = 7$
