Scientific Notation

It is: 2.26*105

If you are adding or subtracting two numbers in scientific notation the exponents must be the same before adding the coefficients. This is similar to 'like terms' in algebraic expressions. You can't add 5x3 and 3x2 because the exponents are not the same.

4 × 109

It is: 5.0*10^-3 g

0.006 = 6 x 10^-3

It is: 5.3*10^3

How do you right 23000 in scienctific notation

2.0 × 102

4.30 * 102. Although numerically equivalent to 4.3*102 the first shows that the number is accurate to 3 significant figures (if that IS the case), and not 2.

The current estimated population of India is 1,170,938,000.

In scientific notation, this is expressed at 1.170938 * 10^8,

or, rounding to the nearest ten thousandth, 1.17 * 10^8

0.0000356 in Scientific Notation = 3.56 x 10-5

1.15 x 10-5

124 in Scientific Notation = 1.24 x 102

0.00050 in Scientific Notation = 5 x 10-4

54,000 = 5.400000e+4

1.56 x 10^-2

8.64 x 107.

3.45 × 10-6

It is: 5.126*10-6

Since the numbers are already expressed in the form a x 10ⁿ, 2 x 104 and 4 x 10-12 are already in scientific notation.

6.833 × 10^13 km^3

3.65 x 10^8

It is: 1.05*10^6
