Answer 1

B) 9.3*107 .................................................

Answer 2

Answer:

B) 9.3 *
`10^(7)` .

Explanation:

Given : 93 million

To find: Express this distance in scientific notation

Solution: We have given that 93 million.

For scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left and to balance , multiply by
`10^(n-1)` .

We can in 93000000 there are 8 digit so we will move the decimal point to 7 digit to left and multiply it by
`10^(7)`

Then number would 9.3 *
`10^(7)`

Therefore, B) 9.3 *
`10^(7)` .
