What do you use decimals for?
Represent numerical values.
What is the definition of numerical analysis?
It is the study of algorithms that use numerical values for the problems of continuous mathematics.
Why everything to the power of zero is equal to 1?
This is easiest to explain with an example. One of the laws of exponents says that division of numbers containing exponents makes the exponents subtract from each other. For example, 24/23 = 2(4-3) = 21 = 2. Expanded to use numerical values, 16/8 = 2. Similarly, 23/23 = 2(3-3) = 20 = 1. It therefore follows that anything to the power zero is equal to one.
How do you express the numbers of a particular prime number using exponents?
Exponents are used to replace repeated factors. Prime numbers won't use exponents because they don't have repeated factors. To express the prime factorization of a particular composite number using exponents, just count. 2 x 2 x 2 x 3 x 3 = 72 23 x 32 = 72
Use exponents to express 7560 as a product of prime factors?
23 x 33 x 5 x 7 = 7,560
