WebMar 17, 2024 · To simplify a square root, we factor the radicand into its prime factors and group any pairs of identical factors together. Next, we take the square root of each perfect square factor and multiply them together outside the radical symbol. The remaining factors are left inside the radical. Start practicing Algebra 1 on Albert now! WebYes, this is fine, provided that a and c have the same algebraic sign. When you solve the second equation, you get. x = c 2 a 2 b. Now try substituting that into the original equation: (1) a b c 2 a 2 b = a c 2 a 2 = a c a . If a and c have the same algebraic sign, c a = c a, and ( 1) can be simplified to a ( c a) = c, as desired.

WebWhen radicals (square roots) include variables, they are still simplified the same way. We just have to work with variables as well as numbers. 1) Factor the radicand (the numbers/variables inside the square root). Factor the number into its prime factors and expand the variable (s). 2) Bring any factor listed twice in the radicand to the outside.

WebTo eliminate a cube root, you need a perfect cube inside the radical (something cubed). You are starting with cuberoot (2). The 2 has an exponent of 1. To create a perfect cube, you need to create 2^3 = 8 inside the radical. Thus we multiply: 1/cubert (2) * cubert (2^2)/cubert (2^2) = cubert (2^2)/cubert (2^3) = cubert (4)/2 Hope this helps.
