Step-by-step explanation:
It is given that,
The average distance between the Earth and the Moon is 384 400 km.
We need to express in in standard form.
1 km = 1000 m
It means,
384400 km = 384400000 km
or
= 
Hence, the average distance between the Earth and the Moon is
.
X= 30
y=18,000(1.04³⁰)=18,000(3.24339751)≈58381
answer: B)58,381
