Scientific Notation
Scientific notation is the expression of a number based on the largest exponent of 10 for its value, where the form is a decimal number A x 10n.

What is the scientific notation for 1500000?
1.5x10^6. In general, when using scientific notation you want to have (some number greater than or equal to 1 and less than 10)x10^(the appropriate exponent). So to get the answer, we'd see that 1500000 = 15x10^5 since there are five 0's and then we'd further reduce it to 1.5x10^6.
What is the exact definition of standard form?
Standard form (also called scientific notation or exponential notation) is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.
How do you write one forty-one thousandths in standard form?
Forty-one thousandths in standard form is written as 4.1 × 10-2
How do you write 7384 using the power of 10?
7.384 x 10^3 or (7 x 10^3) + (3 x 10^2) + (8 x 10^1) + (4 x 10^0)
How do you put things out of scientific notation?
If the exponent is positive, move the decimal to the right the same number of spaces as the number of the exponent. If the exponent is negative, move the decimal to the left the same number of spaces as the number of the exponent.
Examples:
2.5 x 103 is 2500 in standard notation. (Move the decimal to the right 3 spaces.)
4.9 x 10-5 is 0.000049 in standard notation. (Move the decimal to the left 5 spaces.)
What is 70 in scientific notation?
70 in scientific notation is 7 x 101 (might show up as 7E1 on some calculators).
Watch out for significant figures and avoid 7.0 x 101 as the zero is not a sig fig in this case since there is no decimal.
