Question

Take a look at the Picture/math.

Answer 1

2.51 x
`10^(8)`

Explanation:

This is the answer because:

1) All we have to do is subtract 4.9 and 2.39

4.9 - 2.39 = 4.90 - 2.39 = 2.51

2) Next, we just multiply 2.51 with
`10^(8)` which leave us with 2.51 x
`10^(8)`

Hope this helps!

Answer 2

`(4.9 * {10}^(8) ) - (2.39 * {10}^(8) ) \\ =( 4.9 - 2.39) * {10}^(8) \\ = (2.51 * {10}^(8) )`

Option D is the correct answer

Hope this will help...
