Powers and ExponentsPowers and ExponentsObjective: To understand how to represent numbers using exponents.

Powers and ExponentsAt the end of this lesson you should be able to answer the following question.

How is using exponents helpful?

Powers and ExponentsFitness Fortress recycles plastic water bottles. On Saturday, 8 bottles were placed in the bins. On Sunday, 8 bottles were recycled.

Powers and ExponentsYou can use bar diagrams to represent the number of bottles recycled. Use a second bar to represent the number of bottles recycled on Sunday.

8 bottles8 bottlesPowers and ExponentsSome expressions can be written as the product of a sum.

For example, 2 x (1 + 4).

The expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4).

Powers and ExponentsThe expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4).

Which factor is a sum?

Powers and ExponentsThe expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4).

Which factor is a sum? 1 + 4

Powers and ExponentsUsing a bar diagram 2 x (1 + 4) can be written as follows.

Powers and ExponentsNumbers expressed using exponents are called powers.

e.g. 100 is a power of 10 because it can be written as 10.

Powers and ExponentsNumbers expressed using exponents are called powers.

A perfect square is a number that is made by squaring a whole number.

e.g. 100 is a perfect square because 10=100

Powers and ExponentsTo write powers as products, determine the base and the exponent.

e.g. The base of 10 is 10 and the exponent is 2. 10 is read ten squared.

10 is read ten cubed. Powers and ExponentsWhat is the difference between an expression and an equation?Powers and ExponentsWhat is the difference between an expression and an equation?

An equation has an equal sign.

An expression has no equal sign, but has an operation. Powers and ExponentsA number that is squared represents a two dimensional shape.

Powers and ExponentsA number that is cubed represents a three dimensional shape.
