Question

What is the following sum? 5(3√x)+9(3√x)

Answer 1

5(3√x)+9(3√x)
=3√x(5+9)
=14(3√x)

answer is C. third choice 14(3√x)

Answer 2

Option (c) is correct.

`5(\sqrt[3]{x})+9(\sqrt[3]{x} )=14\sqrt[3]{x}`

Explanation:

Given : expression
`5(\sqrt[3]{x})+9(\sqrt[3]{x} )`

We have to choose the correct option from the given options to the sum of the given expression.

Consider the given expression
`5(\sqrt[3]{x})+9(\sqrt[3]{x} )`

Taking
`\sqrt[3]{x}` common from both terms, we have,

`(\sqrt[3]{x})(5+9)=14\sqrt[3]{x}`

Thus,
`5(\sqrt[3]{x})+9(\sqrt[3]{x} )=14\sqrt[3]{x}`
