    great! So we now know this: |dw:1439909078119:dw| Now, what would 0. 75 equal to in scientific notation?

    okaayy.... xD Err, maybe you should try to understand how scientific notation works: https://www.mathsisfun.com/numbers/scientific-notation.html But basically you want to re-write 0.75 with the decimal after the first digit which would be 7 in our case right? So we want 7.5 TIMES 10 to a power. 0.75 = 7.5 x 10^-1 Following??

    |dw:1439909465669:dw| |dw:1439909508652:dw| Now you have to use your exponent laws. |dw:1439909579654:dw|

    Therefore, if we use the exponent rules in the box, we will get: |dw:1439909682894:dw| What does -1 + 20 - 5 = ?

    See how they are both 10^20? This means you just add the 3.7 and 4.45 part ... So like.. say x = 10^20 We have 3.7x + 4.45x = 8.15x if that makes sense?
