#### Transcript of Real life application of exponents (AIM HIGH)

MEDICINE:

-Doctors may use exponents to figure out how quickly a disease is going to spread, as antigens multiply themselves to attack the body.

**Real life applications**

of EXPONENTS by: Anna Sidiangco 9G2

But how do exponents apply to real life situations?

SCIENTIFIC NOTATION:

-Scientist use exponents to measure size of an earthquake. 2 is 2x2x2x2x2. Another way they are used is to measure large distances. For example, the distance from the Earth to the Moon is 1 X 10

km.

BACTERIAL GROWTH:

-One of the most common examples of exponential growth deals with bacteria. Students will use exponential functions to model exponential growth in several real-life situations: spread of flu in a school, bacteria growth. For example, the number of bacteria in a single sneeze is between 1 x 10 and 1 x 10

ENGINEERING:

-Many engineering professions use exponential and polynomial functions in their calculations. For example, computation of the strength of materials used and computation of constructing a bridge.

What are exponents?

COMPUTERS:

-Exponents are often used to describe a computer's memory. For example: 1gigabyte of RAM means that you have 1 x 10 bytes.

Exponents are used in a variety of ways, most often when talking about very big or very small things. Examples are........

pH SCALE:

-Exponents are used to test how acidic or alkalinity a substance is. Instead of multiplying two large numbers, by using logarithms you could turn it into addition (much easier!)
