There are two ways to simplify a fraction exponent such frac 2 3. Use the properties of exponents to simplify. To subtract a positive exponents m and negative exponents n we just connect both the terms by changing the subtraction sign to a positive sign and write the result in the form of m n.

So we just have to say well 9x plus five needs to be equal to zero. Use the power rule to drop down both exponents. By taking the corresponding root unless the exponent is a variable in that case use a logarithm.

This video is part of an online course College Algebra. Do not take logarithms in any other base because your calculator cannot evaluate them Immediately use property 3 of logarithms to bring down the exponent. And we get 9x is equal to negative five.

How to get rid of an exponent using log. Take the log of both sides. Numbr Precision in Excel.

Apply the logarithms rule. Write the expression without fractional exponentsleftfrac16rightfrac32. A lot of people get a little uneasy when they see 0 especially when that 0 is the exponent in some expression.

Take 10 from both sides to eliminate the 10 near the variable. 9x plus five needs to be equal to zero. Check out the course here.

Take the cube root of both sides. After all there seem to be so many rules about 0 and so many special cases where youre not allowed to do something. X³ 125.
