A power learning aid combines Practice, Coaching Calculators and Guides to help students master the solving of radical equations.

Practice and Coaching Calculators cover equations such as :

6√(x ) = 3
3√(2x - 1) = 1
√(x + 28) = x - 2
2√(5 + 3x) = 6x - 4
√(9 − 2x) − √(x) = -1
√(x) + √(x − 5) = 5

The Guide covers these types of equation along with equations such as :

∛(x + 2) = 2

Its ideal for students as the design reinforces each problem solving step.

Examples highlight and simplify algebra that students find hard.
