Take log of both sides. 3 4 81.

### As we know that expression 2 2 is in the numerator we ll simply move it to the denominator to make the exponent positive.

**How to get rid of an exponent in an equation**. Write the expression without fractional exponents left frac 1 6 right frac 3 2. It means you get rid of negative exponents by changing its position in a fraction. Take the cube root of both sides.

You ll get an answer in the form. The result is that the exponential stands alone on one side of the equation which now has the form b f a where the exponent f contains the unknown x. Consider the example of.

When you evaluate this you ll get the same decimal equivalent 2 866 in your calculator. How do i get rid of an exponent in an equation. 3 3 3 3 81.

We can rewrite the expression by breaking up the exponent left left frac 1 6 right 3 right frac 1 2 left frac 1 6 cdot frac 1 6 cdot frac 1 6 right frac 1 2. Otherwise you may as well take logarithms in base 10. Don t be shy about being flexible.

Solve for the value of x if 10 to the 5x power plus 10 is equal to 20. Take 10 from both sides to eliminate the 10 near the variable. Then take the log of each side.

Exponent that is not a variable. X 125. Set up the equation from the information given in the question.

If the base of the exponential is e then take natural logarithms of both sides of the equation. If neither of the above tricks works and you have just one term containing an exponent you can use the most common method for getting rid of the exponent. By factoring out 3 you should see that.

How to get rid of fractional exponents. 10 5x 10 20. How to eliminate exponents in calculus.

Let us see some other examples to make the concept clear. 5ⁿ 125. Solving for an exponent that is when a variable rather than just a number appears in an exponent usually requires the use of logarithms which have handy rules associated with them that help exponent problems.

You need to change 81 to an exponent with a base of 3 so that it matches the other exponential expression in the equation. 2 x 3 5 0 3 1 6 1 7 5 2 42 x small dfrac 350 3 cdot 16 small dfrac 175 24 2x 3 16350 24175. By taking the corresponding root unless the exponent is a variable in that case use a logarithm.

The new equation then becomes. Isolate the exponent term on one side of the equation and then apply the appropriate radical to both sides of the equation. Exponent that is a variable.

1 2 2 which is equal to 1 4. Displaystyle 3 times 3 times 3 times 3 81 so.
