Question

Write any two positive rational numbers and express each in its exponential notation. Also write the base and exponent in each case

Answer 1

Answer:

Exponential notation makes use of the fact that any positive number written in base 10 can easily be expressed as the product of a real number r where 1<r<10 and a power of 10, i.e. as r×10k for some integer k (we here use × to denote the product). Note that k may be negative.

A couple of examples:

345 can be written as 3.45×102

0.39 can be written as 3.9×10−1
