it helps you solve and understand expression faster. it turns long problems it too short ones

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.
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
bacterial growth for one. exponents are used in equations when representing things. growth is the main thing, growth of possibilities(ie. possible outcomes of a situation) another example of a growth calculation would be calculating interest on a loan or a credit card or a savings account (if its compound interest, which most is these days) if you want to get advance, the hardy weinberg equation is used for mapping the gene pool of a population, and it has exponents. also, wave functions of particles. also, it's how ARE exponents used in real live?
One can apply consumer demand management to real life situations in a number of different ways. One way is to manage a business, as it would come it handy.
Scientific notation is a way to write very large or very small numbers using exponents. For example 2000 is 2x103 . We can do the same thing with negative exponents and write very small numbers like 1/2000 which is 2x10-3 . So one real life use of exponents in in scientific notation.

A negative number times a negative number gives you a POSITIVE number, not a negative number.
Usually they don't, unless you work in engineering.

Exponents are based on real life situations. For examle, scientist use exponents to measure size of an earthquake! 2 to the 5th power is 2x2x2x2x2. Another way they are used is when putting in carpeting. You will order 12x12 square inches of carpeting, or 12 Squared.

Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.
