Give two examples that show how using parentheses can change the order in which operations are performed in an expression
Tom [10]

Yes, parentheses can change the order in which operations are performed in an expression.

Let us understand this with two examples.

First example.

Let us suppose we have to simplify the expression

2\cdot (5-3)\\&#10;=2\cdot 2\\&#10;=4

In this expression we have evaluated subtraction first instead of multiply.

Second example.

Let us suppose we have to simplify the expression

(5\cdot 2)- 3\\&#10;=10-3\\&#10;=7

In this expression we have evaluated multiplication first and then subtraction.

Therefore, from above two examples we can see that  parentheses can change the order in which operations are performed in an expression.

Geometric mean for 12 and 3
Tom [10]
Hey there! :D

To find the geometric mean, you multiply the numbers and then find the square root. 

12*3= 36

The square root of 36 is 6.

The geometric mean is 6. 

I hope this helps!
