How to Multiply Radicals. The radical symbol (√) represents the square root of a number. You can encounter the radical symbol in algebra or even in carpentry or another trade that involves geometry or calculating relative sizes or... 3 Multiply Radicals with Different Indices.

Here is a set of notes used by Paul Dawkins to teach his Algebra course at Lamar University. Included area a review of exponents, radicals, polynomials as well as indepth discussions of solving equations (linear, quadratic, absolute value, exponential, logarithm) and inqualities (polynomial, rational, absolute value), functions (definition, notation, evaluation, inverse functions) graphing ...

Roots of real numbers are usually written using the radical symbol or radix , with denoting the positive square root of x if x is positive; for higher roots, denotes the real n th root if n is odd, and the positive nth root if n is even and x is positive. In the other cases, the symbol is not commonly used as being ambiguous.

Radicals (miscellaneous videos). Simplifying square-root expressions: no variables. Dividing by a radical? While you could leave an expression in the form a/sqrt(b), it is more appropriate to multiply that by sqrt(b)/sqrt(b) to what happens if the two roots are different how do you simplify and then solve?
