Answer 1

1.023 x
`10^(14)`

Explanation:

(3.1 x
`10^(8)`)(3.3 x
`10^(3)`)

(3.1 x 3.3)(
`10^(8)` x
`10^(3)`)

10.23 x
`10^(13)` When the bases are the same and we are multiplying we add the exponents

10.23 x
`10^(13)` Is not in scientific notation because 10.23 is larger than 10

1.023 x
`10^(1)` x
`10^(13)`

1.023 x
`10^(14)`
