Answer:
It would be 4:15
Step-by-step explanation:
You would take 20 and 75 and put them in a ratio that would look like this 20:75, then they are divisable by 5 so you reduce them, when you reduce them you get 4:15
lcm for cuberoot
that is 2*2*2*5*5*5*3*3*3
make pairs of three common numbers and write them as one.
2*5*3=30
ans =30
check 30*30*30=27000
cube
multiply 27000 three times with itself
27000*27000*27000
=19683000000000.0
9t²-16u² = 3²t²-4²u² = (3t)²-(4u)² = (3t+4u)(3t-4u)
