Express the mixed radical as an equivalent, entire radical. 1.) 2 ³√7 2.) 4 ³√2 1.) 2 ³√7 {you need to make the 2 into the cube root of a number}
= ³√8 ³√7 {cubed the 2 and put under a cube root sign} = ³√56 {multiplied the two cube roots together} 2.) 4 ³√2 {you need to make the 4 into the cube root of a number} = ³√64 ³√2 {cubed the 4 and put under a cube root sign} = ³√128 {multiplied the two cube roots together} © Algebra House
