Radical expressions are common in the formulas in businesses to calculate the unknown variables about depreciation, inflation and interests. Engineers also use radicals for measurements and calculations. Auto mechanics used radicals to calculate the car engine’s efficiency. Rather than use a calculator to approximate the values of these radicals, they may express the answer as an exact value in radical form. In order for them to obtain the accurate and exact value in the calculations, they must have the knowledge and skills of the different operations on radical expressions.

The learners will be able to:

• Perform operations involving radical expressions.
• Solve simple problems involving operations on radicals.
