Question

Please help me pleaseeee I’ll give lots of points

Answer 1

D. 343

Explanation:

To find the value of x,

First we move all numbers to the R.H.S of the equation.

`\sqrt[3]{x} - 3 = 4 \\ \sqrt[3]{x} = 3 + 4`

Now, we raise each side of the equation to the power 3

`{( \sqrt[3]{x}) }^(3) = {(7)}^(3) \\ x = 343`

Therefore, x is equal to 343.

Answer 2

`\sqrt[3]{x}-3=4\\\text{or, } \sqrt[3]{x}=4+3\\\text{or, } \sqrt[3]{x}=7\\\\\text{Cubing both sides,}\\\\x=7^3\\\text{or, }x=343`
