When a number is in expanded exponential form to a numeral, it means that the leading non-zero digits are separated from the trailing zeroes, which are abbreviate in an exponential termFor example, in the case of 3 x 10^{4}
The leading number is 3 and the exponential term is 10^{4}
10^{4} means 10 to the power of 4, or in other words 10 x 10 x 10 x 10
10 x 10 = 100, 100 x 10 = 1,000, and 1,000 x 10 = 10,000
