Question

Please what’s the answer?… I really need help

Answer 1

$\sqrt[3]{x + 1} = 2$

Let us cube both sides.

$= > (\sqrt[3]{x + 1} ) ^{3} = {2}^{3}$

Now, it will be only x + 1.

$= > x + 1 = 8$

Transpose 1 to the Right Hand Side.

$= > x = 8 - 1$

Now, subtract.

$= > x = 7$

Answer:

x = 7
