Question

What is the simplified form of this expression 7(^3sqrt2x)-3(^3sqrt16x)-3(^3sqrt8x)

Answer 1

`7 \sqrt[3]{2x} - 6 \sqrt[3]{2x} - 6x`

Solution,

`7( \sqrt[3]{2x} ) - 3( \sqrt[3]{16x} ) - 3( \sqrt[3]{8x} ) \\ = 7 \sqrt[3]{2x} - 3 * ( \sqrt[3]{2 * 2 * 2 * 2x} - 3 * \sqrt[3]{2 * 2 * 2x} \\ = 7 \sqrt[3]{2x} - 3 * (2 \sqrt[3]{2} x) - 3 * 2x \\ = 7 \sqrt[3]{2x} - 3 * 2 * \sqrt[3]{2x} - 3 * 2x \\ = 7 \sqrt[3]{2x} - 6 \sqrt[3]{2x} - 6x`

Hope this helps...

Good luck on your assignment...
