Given : The given mathematical problem is, √8+√18
To find : The answer to the given mathematical problem.
Solution :
We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the answer to the given mathematical problem)
Here, we will be using general properties related to square rooting and perfect squares.
So,
= √8 + √18
= √(4×2) + √(9×2)
= 2√2 + 3√2
= √2 (2+3) [Taking √2 common from both]
= √2 × 5
= 5√2
(This will be considered as the final result of the given mathematical problem.)
Hence, the answer is 5√2
