Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (4, 6)

Point (-2, -2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute [DF]: $\displaystyle d = \sqrt{(-2-4)^2+(-2-6)^2}$
Subtract: $\displaystyle d = \sqrt{(-6)^2+(-8)^2}$
Exponents: $\displaystyle d = \sqrt{36+64}$
Add: $\displaystyle d = \sqrt{100}$
Evaluate: $\displaystyle d = 10$

How do you use the order of operations to evaluate expressions with exponents?

IgorLugansk [536]

Using BEDMAS, it would be brackets first, so anything Inside a set of brackets would be solved first, and would follow the same rule. Once the brackets have been solved, next would be the exponents. Since your brackets have been solved you can expand with the exponents. After exponents, would be anything that has to be divided or multiplied. These two operations are interchangeable based on what is more convenient or beneficial to do first. And lastly, addition and subtraction, which once again are interchangeable operations
