## How do you write exponents on Khan Academy?

Powers or exponents Use a caret (^). For example, to enter 4 to the 5th power, type “4^5.”

## Do you do exponents or parentheses first?

The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses in this problem, so start with exponents. Then, multiply and divide from left to right.

## What is the difference between exponents with and without parentheses?

If the base is in parentheses, as in our first case, the exponent affects everything that is inside the parenthesis, that is, the sign and the number. However, if the base is not in parentheses, as in the second case, the exponent affects only the immediate value to the left, that is, only the number, without the sign.

## Is the exponent applied before or after the negative number?

Without parentheses, the exponent is applied before the negative sign. However, if the negative number is in parentheses, then the exponent is applied to the entire negative number. In the expression -3^2, 3^2 is calculated to give 3*3 = 9, then the negative sign is attached to give a final answer of -9.

## When do exponents apply to all parts of the parenthesis?

Direct link to YoWhatUp ImJaredAnd19-‘s post “Of course! It’s mostly seen in this form, though: …” Of course! It’s mostly seen in this form, though: (4^2)^3 where there is one exponent inside the parenthesis then outside the parenthesis there’s another exponent, which applies to all parts inside the parenthesis, including the exponent inside.

## Where are exponents in the Order of operations?

Exponents are near the top of the food chain when it comes to order of operations. Let’s do some examples together. Created by Sal Khan. This is the currently selected item. Posted 5 years ago. Direct link to Anita George’s post “I have a question.

## How are exponents with negative bases used in PEMDAS?

It helps to think of attaching the negative sign as multiplying by -1, and to recall that exponents are performed before multiplication according to PEMDAS. However, in the expression (-3)^2, the exponent 2 is applied to the entire number -3, so (-3)^2 = (-3)* (-3) = 9.
