Question

Explain and give an example of combining like radicals.

Answer 1

Combining like radicals is similar to combining like terms

for example, you know how to combine the following:

x + x = 2x
x^2 + x^2 = 2x^2
3x^3 + 4x^3 = 7x^3

and for radicals, it's no different:
\[2\sqrt{x} + 4\sqrt{x} = 6\sqrt{x}\]
