Can you take the square root of a variable?
If the exponent of the variable is odd, subtract one from the exponent, divide it by two, and write the result to the left of the square root sign, leaving the variable inside the square root sign once, with no exponent.
How do you square a variable?
Squaring a number, or algebraic expression that contains a variable, means multiplying it by itself.
How do you divide square roots?
Correct answer: When dividing square roots, we divide the numbers inside the radical. Simplify if necessary. Let’s simplify this even further by factoring out a.
How do you solve a cubed root?
Set up the problem.
- Write down the number whose cube root you want to find. Write the digits in groups of three, using the decimal point as your starting place.
- Draw a cube root radical sign over the number.
- Place a decimal point above the bar line, directly above the decimal point in the original number.
How do you simplify?
To simplify any algebraic expression, the following are the basic rules and steps:
- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.
