Anatomy of exponential terms.

Example of exponential expression. For example growth occurs in living organisms by the division of cells. But I when I started algebra I had trouble keeping the rules straight so I just thought about what exponents mean. In the following examples students will use their knowledge of exponentiation and rules of exponents to evaluate or simplify various expressions.

Small strategic changes can have a. For example 24 2 4 means to multiply four factors of 2 2 so 24 2 4 means 2222 2 2 2 2. We use exponential notation to write repeated multiplication.

The exponent is written as a superscript number after the base number. Microbes grow at a fast rate when they are provided with unlimited resources and a suitable environment. A number raised to the first power is that number.

Exponential expressions are just a way to write powers in short form. Total number of bacteria count at t0. We can also express that as 2sup5 and we call that an exponential expression.

The a6 means six copies of a multiplied together and the a5 means five copies of a multiplied together. The 10 10 in 103 10 3 is called the base. So in 12 hours the cell will divide 2 2 2 2 2 2 2 2 2 2 2 2 times.

Simplify a6 a5. The product and power rule of. We will see some examples of exponential functions shortly.
