    Good. How do you write that in scientific notation?

    \[7.15*10^{14}\]? You sure about that? \[10^{14} = 100,000,000,000,000\]

    Scientific notation has two parts, mantissa and exponent. The mantissa is that number out from, and it is always between 1 and 10 (or -1 and -10). Come on, stop guessing. D is\[71.5*10^{14} = 71.5*100,000,000,000,000\]

    \[10^0=1\]\[10^1=10\]\[10^2=100\]\[10^3=1,000\]\[10^4=10,000\]\[10^5=100,000\]\[10^6=1,000,000\]\[10^7=10,000,000\]etc.
