Question

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

Answer 1

Answer:

Option (c) is correct.

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

Step-by-step 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, $5(\sqrt[3]{x})+9(\sqrt[3]{x} )=14\sqrt[3]{x}$

Answer 2

5(3√x)+9(3√x)
=3√x(5+9)
=14(3√x)

answer is C. third choice 14(3√x)
