Question

1m = 100cm
1 billion km = 1,000,000,000 km
= 1 x 10^9 km
= 1 x 10^9 x 100 cm
= 1 x 10^11 cm

Can you please explain to me in detail
I am a homeschool student, so really appreciate if you can help

Answer 1

Answer:

there are 9 zeros

so,

1 x 10^9

next,

1x10^9 x 100cm

In this 100 cm has 2 zeros.

so,

1x10^9 +^2

1x10^11.

Answer 2

Answer:

Look it's really easy

Firstly,you know that 1 m = 100 cm = 10²:means 10 is raised to the power 2 where 2 is the number of times

zero occurs in 100.

This same applies to others.
