Nataliya [291]

$38.07 = \frac{9}{100} x$

$38.07 \times \frac{100}{9} = x$

$\frac{3807}{9} = x$

$423 = x$

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

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.

$= > x = 7$

<u>Answer</u><u>:</u>

x = 7

Hope you could understand.
