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}

=

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√8 ³√7 {cubed the 2 and put under a cube root sign}

=
