Solve the Following Problem:
√192 − 3√50 + 2√98 − 2√108
<Answer>
Steps to Solve:
The main goal is to simplify each square root term to the form 𝑎√𝑏, where b is the smallest prime
number or integer that has no square factors other than 1. Once all terms are simplified, we can add or
subtract terms that have the same square root (like terms).
1.Keep it simple √192 find the greatest square factor of 192.
192 = 64 × 3
√192 = √64 × 3 = √64 × √3 = 8√3
2.Keep it simple 3√50 first. The largest square factor of 50 is 25.
50 = 25 × 2
√50 = √25 × 2 = √25 × √2 = 5√2
So,
3√50 = 3 × (5√2) = 15√2
3.Keep it simple 2√98 first. The largest square factor of 98 is 49.
