Scientific Notation

i think it is 8.9x 10<4

16,100.00 in Scientific Notation = 1.61 x 104

27 x 102

2.1 × 10^5

1.2312 x 10^13

It is: 1.4*10^-5

First write it out.

435 billion is 435,000,000,000

Now put a decimal at the end (as long as one did not exist already)

435,000,000,000.

Now move that decimal till it is after the first digit and count how many spots you just moved it.

4.35000000000 (moved 11 spots)

so now we do this

4.35 x 10^11

x 10 ^ k is how you write scientific notation the k is the number of spots you moved it.

More explanation is needed for decimals but you didn't ask for that - so save that for another time.

So, answer to your question 4.35 x 10^11 or on your calculator it may appear 4.35E11

8.91 x 106

or

8.91 * 10^6

9.13 in Scientific Notation = 9.13 x 100

0.07882 = 7.882 x 10^(-2)

7.0 x 109 (approximate, roughly estimated, rounded)

It is 2.11*10^-7 in scientific notation

7.51 x 10^0

0.00811 meters = 8.11 x 10^-3 meters

It is 1.44*102

6.78432*102

Exponents are negative numbers. This is used in math a lot.

1.74*105

3.7 = 3.700000e+0

It is: 9.43*10^-3

It is: 6.8*10^-6

35.9 can be written in scientific notation as 3.59 x 10^1.

5.67 x 10 to the power 2

3.95 x 10-5
