Scientific Notation

To write 0.002 in scientific notation, you first move the decimal point 3 places to the right to get 2. Then, express it as 2 x 10^-3.

0.72 x 10^-4 in scientific notation is 7.2 x 10^-5.

3427 in scientific notation is 3,427 x 10^3

The answer for 12300000 in scientific notation is 1.23 x 10^7.

456.6 in scientific notation = 4.566 x 10^2 or 4.566E2

0.000056 in scientific notation is equal to 5.6 x 10^-5.

0.000382 is 3.82*10^-4 in scientific notation

The scientific notation of 0.0000503 is 5.03 x 10^-5.

9300 in scientific notation is written as 9.3 x 10^3.

The answer for 0.000409 in scientific notation is 4.09 x 10^-4.

The scientific notation for 55000000 is 5.5 x 10^7.

It is 7.8*10^3 in scientific notation

4.2 x 106

Shift a decimal place to the right, so the exponent for base 10 is -1. Then, the term in scientific notation is:

3.456789 x 10-1

6707 can be written in scientific notation as 6.707 x 10^3.

308 million can be written in scientific notation as 3.08 x 10^8

It is: 9.0*10^-7

You subtract the exponent of the denominator from that of the numerator.

100000 in scientific notation is represented as 1 x 10^5.

Suppose you have two numbers in scientific notation.

· Rename them so that the exponents (powers of 10) are the same, · add the two mantissae to form the new mantissa, and append the 10 and exponent, · if the resulting mantissa is 10 or greater then rename the mantissa and adjust the exponent accordingly.
For the first stage you may rename both numbers or either one.

For example,

3.5*10^3+ 4.5*10^4= 3.5*10^3+ 45*10^3= (3.5+45)*10^3= 48.5*10^3= 4.85*10^4
or
3.5*10^3+ 4.5*10^4= 0.35*10^4+ 4.5*10^4= (0.35+4.5)*10^4= 4.85*10^4

The number 85000 in scientific notation is 8.5 x 10^4.

The correct scientific notation for 160000000 km is 1.6 x 10^8 km.

The scientific notation for 7001000000000 is 7.001 × 10^12.

8350 in scientific notation is 8.35 x 10^3

370 billion in scientific notation is 3.7 x 10^11.
