Express the mixed radical as an equivalent, entire radical.
1.) 2 ³√7
2.) 4 ³√2
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}
