Express in scientific notation. Remember, M must be a number 1 ≤ M < 10.

32,400 =

3.24-4
3.24*10-4
3.2400*10-4

the dash means to the 4th power

can anyone help me?

correct,

use 10^4 to show 10 raised to the fourth

thank you :)

To express 32,400 in scientific notation, you need to write it in the form M x 10^n, where 1 ≤ M < 10.

First, let's count the number of zeros in 32,400. There are four zeros.

Next, we need to move the decimal point to the left until we have a number between 1 and 10. In this case, we need to move the decimal point four places to the left.

So, 32,400 can be expressed as:

3.24 x 10^4

Remember that the exponent represents the number of places the decimal point was moved. In this case, the decimal point was moved four places to the left, so the exponent is 4.

Therefore, 32,400 can be expressed in scientific notation as 3.24 x 10^4.
