equals forty Wynant's multiplied by itself three times Yeah well

the answer choice is always out Tio foil the questions

Plans whisper another secret Hey we all contain a cube

root So there's no hole number That equals forty when

it's cubed look for perfect cube factors of forty instead

Yeah That's How all these questions talking like a moron

All right well don't mind if we do We follow

the road here The factor pairs of forty are ten

and four five and eight two and twenty And of

the factors listed well eight is the only perfect cube

right to tend to tend to so used a factor

Pair of eight and five to rewrite Forty When we

get to cuba to forty is the cube root of

eight times five which is equivalent to the cube root

of eight multiplied by the cube root of five And

well we know the cube root of eight There is

to so we just multiply right Took two times cuba

to five That's a simplified form of the cube root

there and hopefully fall for neither trick questions they threw

at you That's it forty is two times cuba to

five and the answer is a and we're done We're

shmoop
