Answer:
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
