Write each number in scientific notation:

1) 15.01
ans. Is it 15.01 x 10 minus to the power of 2?? Am i wrong?

Yes, you are wrong.

1.501*10^1 would be one way to write it in scientific notation. There are others, such as 0.1501*10^2.

You are almost correct! In scientific notation, we express a number as a product of a number between 1 and 10 (the coefficient) and a power of 10.

For the number 15.01, we move the decimal point two places to the left to get a coefficient between 1 and 10. So, it becomes 1.501.

Now, we can express it in scientific notation as 1.501 x 10^2 (or 1.501e2).

You are close! In scientific notation, we express a number as a product of two factors: a decimal number between 1 and 10, and a power of 10. To write 15.01 in scientific notation, we need to move the decimal point two places to the left so that the decimal number becomes 1.501. Since we moved the decimal point to the left, the exponent of 10 will be positive. Thus, the correct scientific notation for 15.01 is 1.501 × 10^2.
