f(x)=1/512 = 1/8^3 = 8^-3
I understand that 8^3 equals 1/512, just not what steps they took. Is there an easy way to figure out the exponential form of a number? Also, why did the exponent become negative at the end step?
Thank you. Answer by ewatrrr(24785) (Show Source):
Hi,
As to 512 being 8^3 ... some just know that...
others arrives at that by experimenting dividing 512 by logical selections.. like an 6 or 8 ****** ********
