Question

$3\sqrt{6}+4\sqrt{6}$ is equal to?

Answer 1

$3\sqrt{6}+4\sqrt{6}$

Since the given numbers are like radicals and the radicands and the index are the same the addition of given numbers can be done as follows

Add the like radicals by adding their coefficients:

$(3+4)\sqrt{6}=7\sqrt{6}$

Hence, the required answer is $7\sqrt{6}$.
