The exponents are added.
Use the properties of powers. In this case, you can combine powers with the same base, by simply adding the exponents.
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
You add the exponents- x^2*x^6=x^8
ummm........ i forget
Rene' Descartes
Archimedes is said to have invented exponents to express very large numbers. A passage from The Sand Reckoner is offered as evidence. To say that he invented exponents is a stretch of the facts; but he was aware of the concepts involved.
Because the expressions are undefined for base = 0.
Exponents can simplify very ugly math problems and their relation to logarithms makes them invaluable. FYI logarithms were invented before exponents.
Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same).
i don no:(
The physical properties of materials are not invented, they are intrinsic, natural, specific characteristics of any material.
The triangle was not invented. It is the result of observations of physical properties.
The exponents are added.
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
Antifreeze properties of some liquids were known about long before cars were invented.
