Standard Form

Standard form, also known as scientific notation, is a way of writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.

Examples

To convert a number to standard form means to write it in the form a x 10^b where a is a number greater than or equal to one and less than ten and b is an integer.

34800

= 3.48 x 10000

= 3.48 x 10 x 10 x 10 x 10

= 3.48 x 10⁴

0.0348

= 3.48 ÷ 100

= 3.48 x ¹⁄₁₀₀

= 3.48 x 10^-2

Finally note that any number raised to the power zero is 1 so:

3.48

= 3.48 x 1

= 3.48 x 10⁰

3.2 × 10⁵ + 2.3 × 10⁵ = ×10	5.1 × 10⁵ + 8.7 × 10⁵ = ×10	3 × 10¹ + 9 × 10⁰ = ×10
2.8 × 10⁴ − 1.6 × 10³ = ×10	3.9 × 10⁷ − 4.8 × 10⁶ = ×10	2.9 × 10² − 7.4 × 10⁰ = ×10
4 × 10² × 3 × 10⁴ = ×10	9 × 10⁵ × 7 × 10³ = ×10	7 × 10³ × 2 × 10⁵ = ×10
9 × 10⁵ ÷ (3 × 10²) = ×10	3 × 10⁴ ÷ (5 × 10¹) = ×10	9.92 × 10¹ ÷ (2 × 10⁴) = ×10
