Question

What is the order of 1.5 x10^3, 1.4 x 10^-1, 2 x 10^3 and 1.4 x 10^-2 from least to greatest?

Answer 1

order the numbers based on the powers of 10

the higher the the positive power the larger the number...

its just like the number line... the further left the smaller the number

if powers are equal... then look for the larger number

in your question the order is

1.4 x 10^-2 , 1.4 x 10^-1, 1.2 x 10^3, 1.5 x 10^3
