Scientific notation, and standard form..?

Question

36000X10^10?

in standard form.

and 0.0000403X10^12

also 0.0000000082

0.000000000205

in scientific notation?

Answer 1

Scientific notation is the smallest or simplest way to express any given number. It is idea for scientists of all sorts.

3.6 * 10^14 is the most simple way of expressing that number.

Answer 2

36000X10^10?

in standard form.  is  move decimal 10 places to the right

360,000,000,000,000

and 0.0000403X10^12  12 to the right

40,300,000

also 0.0000000082=  8.2 x 10^-9

0.000000000205 = 2.05 x 10^-10

in scientific notation?

Answer 3

36000X10^10 = 360000000000000

0.0000403X10^12 = 40300000.00

0.0000000082 = 8.2x10^-9

0.000000000205 = 2.05x10^-10

Answer 4

You just move the decimal.  Like the first one would be 360000000000000...add 10 0's

Answer 5

3.6 X 10^14

4.03 X 10^7

8.2 X 10^-9

2.05 X 10^-10

Standard form only has one number before the period, so you have to move the decimal point whatever number of places to the right or left until you have one number to the left of the decimal point.  When you move the decimal place left, you add one to the exponent of 10 for each place you move the decimal point to the left.  When you move the decimal place to the right, you subtract one from the exponent of 10 for each place you move the decimal point to the right.

Answer 6

360,000,000,000,000 (just add ten 0's)

40,300,000 (move the decimal to the right 12 times)

8.2 x 10 ^ -9

2.05 x 10 ^ 10
