Simplify.

4√6+2√6−√6

a- 5√18
b-5√6
c-6√6
d- 6√18

B

Step-by-step explanation:

Simplifying radicals is similar to collecting like terms in algebra.

Here, the like terms are the radicals

Given

4 + 2 -

= (4 + 2 - 1 )

= 5 → B

B. 5√6

Step-by-step explanation:

These are all like terms or like radicals so we can just do the operations. When we say like radicals they have the same root and radicand.

ex.

√ab and √ab

3√3 and 2√3

Notice that both have √3, same root and same radicand so they are like terms.

Now going back to your problem:

4√6 + 2√6 - √6

Just add/subtract the coefficients and copy the radicand since they are like radicands.

4√6 + 2√6 - √6

= 6√6 - √6

= 5√6
