Scientific Notation

4 × 109

It is: 2.26*105

Yes, scientific notation can be negative. For example -345 would be -3.45 x 102.

0.0081 in scientific notation is 8.1 × 10-3

7.65x10-8

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.

3.65 x 10^8

It is 3.1*10^-3 in scientific notation which is equivalent to 0.0031

It is: 1.05*10^6

8.64 x 107.

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

2.0 × 102

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.
