An acceptable way to type an exponent is to use the caret symbol (^). Example: Write 3 to the power of 2 as 3^2. If possible, superscripts are normally used. Example: write 10 to the power of 5 as 105.
In those countries that use the long scale (based on powers of a million) eg Europe:1 trillion = million3 = 1018 ⇒ 211/2 trillion = 2.15 x 1019, ie exponent is 19.In those countries that use the short scale (based on powers of a thousand), eg USA:1 trillion = thousand x thousand3 = 1012 ⇒ 211/2 trillion =2.15 x 1013, ie exponent is 13.
A rational exponent is an exponent in the form of a fraction. Many financial formulas use rational exponents. Compound interest is formula that uses rational exponents.
64 ( six to the fourth power) Exponents indicate the number of times that the base (6 in this case) is multiplied by itself. In this example, it's being multiplied four times, so we use the exponent 4.
