Getting rid of exponents

Q:  Re-write: 4.85 x 10^0 without exponents.

A:  First we must learn an important exponent rule:

10^0 = 1… 7^0 = 1…. 5^0 = 1… See the pattern?  By definition, anything to the zero power equals 1.  There is one exception: 0^0 — this is undefined, but it is also something you won’t have to worry about for now.  So, just remember:  anything^0 = 1.

So, now start with the problem:

(4.85)* (10^0) = (4.85) * (1)

[since 10^0=1, right?]

And, (4.85)*(1) = 4.85

So, there you have it…. (4.85)* (10^0) = (4.85) * (1) = 4.85

Not too bad, huh?
