Question

Solve the multiple choice problem below & select which answer is correct.

Answer 1

Option A

Explanation:

Two surds can be added (or subtracted) if the radicands (the number under the root symbol) are the same.

From the given options, the expression that could be simplified without first simplifying the individual radical expression is:

`2 √(50)+5 √(50)`

To simplify this expression, we simply add the products 2 and 5 respectively to obtain:

`2√(50)+5√(50)=7√(50)`

The correct option is A.
