# Radicals and Rational Exponents and Applications of Logarithms

While the radical symbol is widely used, converting to rational exponents has advantages. Explain an advantage of rational exponents over the radical sign. Include an example of an equation easier to solve as a rational exponent rather then a radical sign.

2)The loudness of sound is based on intensity level measured in decibels using a logarithmic scale and is relative to (a ratio of) the weakest sound the ear can hear.

How is sound measured. The formula for measuring sound.

What would be a specific sound, give me the decibels of the sound, and please explain what this measurement means. If you have a reference I would like to see it and check it out also)

3)Using the index of a sequence as the domain and the value of the sequence as the range, is a sequence a function?

Which one of the basic functions (linear, quadratic, rational, or exponential) is related the arithmetic sequence?

Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric sequence?

I need to find at least two real-life examples of a sequences or series. One example, I know is arithmetic, and the second is geometric. How can I explain these examples would affect me personally.
