Solve the equation r3 = 216.

r3=216

I found three solutions

1. r =(-6-√-108)/2=-3-3i√ 3 = -3.0000-5.1962i

2. r =(-6+√-108)/2=-3+3i√ 3 = -3.0000+5.1962i

3. r = 6

choose 1,2 or 3

r=72

Step-by-step explanation:

it is r3 = 216 so ris multiplied by 3 so the opposite of multiplication is division so it is 216/3 which is 72 so r=72

true

step-by-step explanation:

the answer is y = 11.54

hope this : )
