How do I get rid of an exponent in an equation? By taking the corresponding root, unless the exponent is a variable, in that case use a logarithm.
All of these require you to:
- simplify both sides to an exponential with the same base.
- set their exponents equal to one another.
- solve for the unknown.

How do you get rid of an exponent of 3?
The opposite of an exponent of 3 is a cubed root, indicated by this symbol: ³√.
How do you reverse an exponent?
Answer and Explanation: Thus we see, that to reverse exponents, we take the root. Therefore, the inverse operation of raising to an exponent n is taking the nth root.
How do you get rid of an exponent with a log?
To rid an equation of logarithms, raise both sides to the same exponent as the base of the logarithms. In equations with mixed terms, collect all the logarithms on one side and simplify first.
What is the sum of ¼ and ¼?
1/4 + 1/4 = 12 = 0.5
Spelled result in words is one half.
What is a half exponent?
If an exponent of a number is a fraction, it is called a fractional exponent. Exponents show the number of times a number is replicated in multiplication. For example, 42 = 4×4 = 16. In the number, say x1/y, x is the base and 1/y is the fractional exponent.
What is 9 to the power of half?
3
Answer: 9 to the power of 1/2 is 3.
What is 2 to the power half?
Answer: 2 to the power of 1/2 is √2 or 1.4142… Let’s solve this question step by step. Hence 2 to the power of 1/2 can be written as 2(1/2) which is a fractional exponent.
What will happen if the exponent is negative?
A negative exponent takes us to the inverse of the number. In other words, a–n = 1/an and 5–3 becomes 1/53 = 1/125. This is how negative exponents change the numbers to fractions. Let us take another example to see how negative exponents change to fractions.
How do I uninstall log10?
Correct answer:
Explanation: In order to eliminate the log based ten, we will need to raise both sides as the exponents using the base of ten. The ten and log based ten will cancel, leaving just the power on the left side. Change the negative exponent into a fraction on the right side.
What is .75 as a fraction?
3/4
Answer: 75% is written as 3/4 as a fraction in its simplest form.
What is sum math?
A sum is the result of an addition. For example, adding 1, 2, 3, and 4 gives the sum 10, written. (1) The numbers being summed are called addends, or sometimes summands.
How do I subtract fractions?
There are 3 simple steps to subtract fractions
- Make sure the bottom numbers (the denominators) are the same.
- Subtract the top numbers (the numerators). Put the answer over the same denominator.
- Simplify the fraction (if needed).
How do you get rid of a fraction exponent?
How to get rid of fractional exponents. Write the expression without fractional exponents. We can rewrite the expression by breaking up the exponent. We need to rationalize the denominator.
Can exponents be decimals?
Usually you see exponents as whole numbers, and sometimes you see them as fractions. Rarely do you see them as decimals. When you do see an exponent that is a decimal, you need to convert the decimal to a fraction. Then, there are a number of rules and laws regarding exponents you can use to calculate the expression.
