Question

Can someone please help me? I’m confused.

Answer 1

`1.50000` ×
`10^(-5)`

Explanation:

Simplify:

1. 
   `2` ×
   `10^(3)` =
   `2000`
2. 
   `6` ×
   `10^(4)` =
   `60000`
3. 
   `8` ×
   `10^(12)` =
   `8000000000000`
4. Re-write expression:
   `((2000)(60000))/(8000000000000)`

Simplify the numerator:

1. 2000 × 60000 = 120000000
2. Re-write expression:
   `(120000000)/(8000000000000)`

Divide:

1. 120000000 ÷ 8000000000000 = 0.000015

Convert to scientific notation:

1. 
   `0.000015 = 1.50000` ×
   `10^(-5)`

I hope this helps!
