6.5 Solving Square Root and Other Radical Equations p390

To solve a radical equation, isolate the radical and then raise each side to the power suggested by the index. Check for extraneous solutions. Ex) Solve

To solve an equation of the form isolate the rational exponent. Then raise each side to the reciprocal power. When taking an even root, remember that you must allow for a positive and negative solution. Check for extraneous solutions. Ex) Solve

To solve an equation of the form isolate the rational exponent. Then raise each side to the reciprocal power. When taking an even root, remember that you must allow for a positive and negative solution. Check for extraneous solutions. Ex) Solve

Ex) Solve for V.

Ex) Solve

To solve an equation with two radicals or rational exponents, isolate one of the radicals (or one of the rational exponent terms) and eliminate it. Then repeat. Check for extraneous solutions. Ex) Solve
