Question

what is 2.8, 2.8 times ten to the second power, 2.8 times 10 to the negative third power, 2.8 times ten to the fourth power in order from lease to greatest

Answer 1

Written out in scientific notation, this looks like:

2.8 x 10^0, 2.8 x 10^2, 2.8 x 10^(-3), 2.8 x 10^4

With scientific notation, what you have to remember is that the exponents following the 10 are what matter.

If the exponent is positive, the number is getting bigger, so the bigger the exponent, the bigger the number.

If the exponent is negative, the number is getting smaller, so the larger the exponent, the smaller the number.
