21 to the forth power
It is 1.818x10 raised to the power of 3.
It means in powers as for example 5*5*5 in exponential notation is 5^3 which means 5 to the power of 3
Exponents are used in many different contexts and for different, though related, reasons. Exponents are used in scientific notation to represent very large and very small numbers. The main purpose it to strip the number of unnecessary detail and to reduce the risk of errors. Exponents are used in algebra and calculus to deal with exponential or power functions. Many laws in physics, for example, involve powers (positive, negative or fractional) of basic measures. Calculations based on these laws are simper if exponents are used.
This means multiply the base times itself as many times as the exponents says. Ex: 4 x 4 x 4 =64 4 to the power of 3 = 64
3.9476 x 101
something like this: 5 to the power of 2 would be written as exponential notation like: 5²
Exponential notation is a useful way of writing big numbers. Exponential notation means "to the power of...". For example: 24 means 2x2x2x2 (2 times itself three times) 10^8 (another way of writing exponential notation) means 100000000 (1 with 8 zeros after it).
