Order of Operations

Today, in class we learned about order of operations..

the number in front of the power is called the coefficient.

the power is made up of the base-which is the 6

exponent- 2

The next question that we did worked on is..

use B.E.D.M.A.S.

Convert the next step into a fraction..

The next problems that we did were..

We have to find the exponent that equals the same as 81^4 and 8^3 with the base of 3 and 2.

Trisha's Blog Question

01. Calculate the dimensions of a square that has the same area as a circle with a radius of 5.7 cm. Round your answer to the nearest tenth of a centimetre.

A= √πr^2

A= √π5.7^2

A= √102.1

A= 10.1

The dimensions of a square that has the same area as a circle is 10.1 cm.

In Class yesterday, Mr. Backe gave us some questions..

Another question he gave us..

The Faster Way

Product Law: When the bases are the same, simply add the two exponents to get the new power.

Product law means multiplying.

The faster way..

Another question..




Quotient Law: When the bases are the same, simply subtract the two exponents to get the new power.

Power of a power law: When a power is raised to a power simply multiply the two powers together to get the new product.

Another question



Another Question..








When a product is raised to an exponent, you can rewrite each number in the product with the same exponent.




Power of a quotient: When a quotient is raised to an exponent, you can rewrite each number in the quotient with the same exponent.

Powers & Exponent











Power of zero it will always be 1
any number or variable to an exponent of 1 is always itself
any exponent of 2 is always a perfect square and always an area
anything to an exponent of 3 represent perfect cube and represent volume

Lorriel's Textbook Question

Chapter 2.4 page 81

Question# 33

A square has an area of 32cm². What is the area of the largest circle that will fit inside it ? Express your answer to the nearest tenth of a square centimetre.

A= s²

√32cm= √s²

d= 5.7 r= 0.83

πr²= 8.949

2.83x2.83x3.14 = 25.1

Jieram's Textbook Question

Chapter 2.4 Page 79

Question 16 a)

The label on a 1-L can of paint states that the paint will cover an area of 10m^2. What is the side length of the largest square area that the paint will cover? Express you answer to the nearest hundredth of a metre.

To find the answer we have to get rid of the exponent. To do that square root 10.

I get..

but remember to round it to the nearest hundredth.

So I get 3.16

If you multiply 3.16 by 3.16 we get 9.98 or 10

The side length of the largest area that a 1-L can of paint can cover is 3.16
