150,000,000

Answer 3

@ryanL. how did you got 1.5*10^8 km. can you show how please.

Answer 4

\[m*10^3 =km\]
so we use this conversion
\[ \frac{km}{m*10^3}\]
\[1.5*10^{11}m * \frac{km}{m*10^3}= \frac{1.5*10^{11} km}{10^3}= 1.5*10^8km\]

Answer 5

@RyanL. can you help me on this problem to check if I got it right. 6.23*10^-7m= nm

Answer 6

I got 6.24*10^4nm and it seems wrong.

Answer 7

6.23*10^2 nm

look at the conversion

Answer 8

@RyanL. can you show me

Answer 9

1m= 1*10^9 nm

Answer 10

you will need to multiply what you have by

10^9 in order to convert it to nano meters.

Answer 11
