Radicals, Exponents & Functions
Move between radical and exponent notation, solve carefully, and use function language to describe inputs, outputs, and inverses.
Direct answers and concept explanations that make the structure visible.
03Algebra · Concept explainerRational exponents: the bridge between powers and rootsThe denominator names the root and the numerator names the power. This notation lets radical expressions use the ordinary exponent rules.04Algebra · Concept explainerFunction notation: inputs, outputs, and what f(x) does not meanf(x) names the output of function f at input x. The parentheses indicate evaluation, not multiplication.06Algebra · Concept explainerExponential growth and decay: reading the modelSeparate the starting amount from the repeated growth factor, then connect each parameter to a real change per time interval.
Repeatable procedures with worked examples and checks.
01Algebra · Method guideSimplifying radicals by pulling out perfect powersFactor the radicand into a perfect power times what remains. Pull only complete groups through the radical bar.02Algebra · Method guideSolving radical equations and checking for extraneous rootsIsolate one radical, raise both sides to the matching power, solve, and check every candidate in the original equation.
