When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)

How do you write 32000000 in scientific notation?

scientific notation is a single digit or digit and decimal followed by the letter E and the exponent of ten to be multiplied by the number.(or number of places to shift the decimal point to the right(positive exponent) or left(negative exponent)) 32000000 would be expressed as 3.2E7

How do you put a number into scientific notation?

To put a number into scientific notation, first identify the decimal point's position to get a number between 1 and 10. Then, write this number followed by the multiplication sign "×" and 10 raised to the power of the decimal places the decimal point moved. If the decimal point moves to the left, the exponent is positive, and if it moves to the right, the exponent is negative.


How do you write 8.2 in expanded form?

If you're talking about scientific notation you would take a number, for example, 0.00000056 and move the decimal to the rightso you have a number before and after the decimal (this case 5.7) and count how many place you move the decimal in this case 7. So to write it in scientific notation it would be 5.7 X 10 and 10 would have a ngative exponent, negative because the numbe is a decimal and we moved the decimal to the right. The exponent would be the number of places you move the decimal, 7. The scientific notation of 0.00000056= 5.6 X 10 to the negative seventh (-7 exponent) power. But to put it in it's expanded or original form you would have an equation like 5.6 X 10 to the -7th power. You would write out 5.6, and because you are multiplying by 10 you just have to move the decimal the number of places the exponent is and because the exponent is negative to the left for positive exponents to the right. So you have 5.6 and it's multiplyed by 10 with a negative exponent of 7 you would take the decimal and move it to the left 7 times so you get 0.00000056. The scientific method is just a simpler way of writing out long numbers with a lot of zeros. NOTE: If you have a positive exponent you move the decimial to the left to get scientific notation and right for expanded or original form.

How do you write 2.92 x10 negative 1 exponent in standard form?

The -1 exponent is stating that the decimal needs to be moved one place to the left (essentially making the number smaller than how it appears).The standard form would be shown as: 0.292If the exponent were to have been a positive 1, the decimal would move one place right, instead of left.

What are the rules in changing exponential number to common number?

For a positive exponent, move the decimal point to the right, as many digits as indicated by the exponent. Fill out with zeroes as needed. Example: 5.3 x 103 = 5300 (there is an implicit decimal point at the end; you can write it explicitly as 5300.0). For a negative exponent, move the decimal point to the left. Again, fill out with zeroes as needed. Example. 2.3 x 10-6 = 0.0000023
