Answer:
69.12
Step-by-step explanation:
The ratio between the masses of Jupiter and Venus is

We can separate the coefficient and the powers of ten:

Use the exponent rule

to simplify the powers of 10:

So, the ratio is

So, Jupiter has a mass that is approximately 400 times greater than Venus's.
The smallest number that has 1 2 3 4 5 as factors is: 3x4x5 = 60
The special name is Least Common Multiple, because 60 is the LCM of 1, 2, 3, 4, and 5
The answer is n = d/4 + 1/2
