b.170
c.2.5
d.2

Answer 1

The answer is choice A. 200

Answer 2

`3.4 * 10^(10)` 200 times greater than
`1.7 * 10^8`

Explanation:

`3.4 * 10^(10)` and
`1.7 * 10^8`

To find how many times greater is
`3.4 * 10^(10)` than
`1.7 * 10^8`, we divide the exponents

`(3.4*10^(10))/(1.7*10^8) =(2*10^(10))/(10^8) = 2*10^2`

2*10^2 = 2*100=200

`3.4 * 10^(10)` 200 times greater than
`1.7 * 10^8`
