If this equation had asked me to Solve 2 x 32 then finding the solution would have been easy because I could have converted the 32 to 2 5 set the exponents equal and solved for x 5But unlike 32 30 is not a power of 2 so I cant set powers equal to each other.

How to solve for an x in the exponent. Lets assume you need to solve the exponent by hand and your number is 4 3. The base is the big number in an exponential expression. For example say wed like to solve for x x.

I need some other method of getting at the x because I cant solve with the equation with the variable floating up there. The next step in how to solve exponent is to multiply the base by the base number only and to the times mentioned in exponent. We can verify that our answer is correct by substituting our value back into the original equation.

10 x 10 x 10 x 10 x 10 x 10 x 10 10 7 Example 3. Raise both sides to multiplicative inverse of the exponent simplify. Example 1Solve for x in the equation.

Solve x frac23 1 65 Step 1. Exponents and Powers Applications. Scientific notation uses the power of ten expressed as exponents so we need a.

Since the exponents are equal and have the same base their exponents. One of the methods of solving X is to isolate the x on one side and then you have to shift the other numbers in the equation to the other side. Free online calculators for exponents math fractions factoring plane geometry solid geometry algebra finance and more.

Where x is in the exponent BUT the bases DO NOT MATCH. Using this gives 2 2 5 9 x 2 3 x 2 2 2 5 9 x 2 3 x 2 So we now have the same base and each base has a single exponent on it so we can set the exponents equal. Determine whether the two exponents have the same base.

A m b m ab m. Solve Exponential Equations for Exponents using X logB logA. You can only use this method when.

4 3 4 x 4 x 4. To solve an exponential equation take the log of both sides and solve for the variable. To do this we simply need to remember the following exponent property.

If the exponent is an odd power there is only one solution. Use the power rule for logarithms to rewrite a logarithm Use the power rule for logarithms to solve an equation containing the variable in an exponent Sometimes the variable of interest in an equation is contained within an exponent. Whenever an equation contains all even exponents you should consider both the positive and negative solutions.

For example Your equation is X 9 16. Isolate the exponential expression. Now you can solve it by writing the number with multiplication for the times mentioned in exponent.

Get your exponential expression on one side everything outside of the exponential expression on the other side of your equation. Will calculate the value of the exponent. Simplify 25 3 5 3 Solution.

4x1 49 Step 1. Ignore the bases and simply set the exponents equal to each other x 1 9 Step 2. If the numbers are positive on one side then it will become negative when you shift to the other side.

Lets get some practice solving some exponential equations and we have one right over here we have 26 to the 9x plus 5 power equals 1 so pause the video and see if you can tell me what X is going to be well the key here is to realize the 26 to the 0th power to the zeroth power is equal to 1 anything to the zeroth power is going to be equal to 1 0 to 0 power we can discuss it some other time but anything. Solve for the variable x 9 - 1 x fbox 8 Check. 25 3 5 3 can be written as 255 3 5 3 125.
