What is an exponent ?

The exponent of a number says how many times to use the number in a multiplication.

In 82 the "2" says to use 8 twice in a multiplication,

so 82 = 8 × 8 = 64

Zero raised to any power is zero (e.g. 0^5 = 0)

One raised to any power is one (e.g. 1^5 = 1)

Any number raised to the zero power is one (e.g. 7^0 = 1)

Application in Medicine

In nursing, dosages of medicine are indicated in powers of 10.

For example, a nurse might have to to convert 0.032 l to 32

More likely, he or she would have to understand that a dosage like 0.8 ml is a tenth of 8 ml and read it accordingly on a measuring device (cup, hypodermic, setting on a drip mechanism).

Application in Computer

Exponents are often used to describe a computer's memory.

E.g: 1 gigabyte of RAM means that you have 1 * 10 to the power 9 bytes.

Computer programmers use their understanding of exponents to determine the most efficient way to write a computer program and the minimum specifications a computer requires for a program to work.

Application in Richter Scale

The strength of earthquakes is described by a number from 0 to 9 on the Richter scale. The Richter scale is an exponential scale which uses powers of 10 to compare the magnitude or size of earthquakes.

This means that an 8 earthquake is ten times stronger than a 7 earthquake.

Application in Architecture

Exponents are used regularly in measuring area.

For example, suppose an architect is asked to design a single-story house that measure 1,500 square feet. The term "square feet" refers to an exponent, in this case feet x feet. The architect must know how to use exponents in order to accurately plan a house of the required area.

Exponents are also called

Powers

or

Indices

.

Both doctors and nurses use math every day while providing health care for people around the world.
