Question

Express the following in standard form 178000000km

Answer 1

1.78 x 10^8

Explanation:

178000000

I usually count the number of zeros first so in this case, it would be 6

178 x 10^6

This wouldn't be standard form because the number should be between 1 and 9

178 ÷ 100 = 1.78

I divided this number by 100 so I would times 10^6 by a 100

10^6 x 100 = 10^8

the answer would be 1.78 x 10^8

i hope this helps!

if it is confusing then i am sorry
