Question

Which of the following is a like radical to 3 sqrt 7x?

Answer 1

Answer:

Options A and B

i.e., A. 4(3$\sqrt{7x}$) and B. $\sqrt{7x}$

Step-by-step explanation:

Like radicals are similar to like terms.

For example,

x, 2x, -10x, $\frac{1}{2} x$, 7.3x are like terms.

$xy^{2} , -9xy^{2} , 13y^{2} x$ are some more examples of like terms.

Similarly, like radicals are:

$\sqrt{2} , -5\sqrt{2} , 1.1\sqrt{2}$ etc.

Hence, from the given options, like radicals to $3\sqrt{7x}$ are:

A. $4(3\sqrt{7x} )$ and B. $\sqrt{7x}$
