How to solve 4 to the power of x equals 8. Write a new equation that sets the bases equal to each other. When multiplied bases are raised to an exponent the exponent is distributed to both bases. Get step-by-step solutions from expert tutors as fast as 15-30 minutes.
Tap for more steps. 2 x 4 0 9 6. Cancel the common factor of 4 4.
Take the logarithm of both sides of the equation. In this part weve got some issues with both sides. Apply the power rule and multiply exponents a m n a m n a m n a m n.
Z 2 z 5 z 2 z 10 z 10 z 2 z 5 z 2 z 10 z 10 So after all that work we get a solution of z 10 z 10. Enter the Equation you want to solve into the editor. 7 8 7 8.
Exponents are shorthand for repeated multiplication of the same thing by itself. Solve x 4 8 7 8. 2 2 4 2 2 4 2 8 256.
You can put this solution on YOUR website. The right-hand side is easy. Click the blue arrow to submit and see the result.
Now your equation can be written as. X 4 7. Since taking the log of negative numbers causes calculation errors they are not allowed.
2 4 2 8 2 64. 8 to the x equals 4. However both 8 and 4 are powers of 2 so I can convert.
Absolute and radical equations step-by-step. When exponents are raised to another exponent the exponents are multiplied. To multiply values with a.
Cancel the common factor. This process of usin. Learn how to deal with Rational Powers or Exponents.
Log 2 xlog 4096 lo g 2 x lo g 4 0 9 6 The logarithm of a number raised to a power is the power times the logarithm of the number. This equation is similar to the previous two but is not quite the same because 8 is not a power of 4. Take the logarithm of both sides of the equation.
Use the rules of exponents and logarithms to solve the equation. 9x 3 32x 3. Again you have two exponential expressions that are equal to each other.
This calculator will solve for the exponent n in the exponential equation x n y stated x raised to the nth power equals y. 9 to the x power equals 3. Since 8 and 4 are both powers of 2 we can solve this quickly easily and without logarithms.
Enter x and y and this calculator will solve for the exponent n using log. 9 to the x power equals 3. D 459x 1 8x2 4 5 9 x 1 8 x 2 Show Solution.
8 2 3. Thus 9m 32m 3 2m 8134. Your first 5 questions are on us.
Answer by jsmallt9 3758 Show Source. A b n a n b n. The equations section lets you solve an equation or system of equations.
You can usually find the exact answer or if necessary a numerical answer to almost any accuracy you require. In this case both sides have the same exponent and this means the bases must be equal. The inequalities section lets you solve an inequality or a system of inequalities for.
Two powers of 2 cannot be equal unless their exponents are equal. Can you solve for x. The left side can be simplified further by using properties of exponents.
Raise 3 3 to the power of 3 3. X solve for x. First the right side is a fraction and the left side isnt.
X 4 8 7 8. Solve4 2 x 2 2 x 8mathbf color green 4 2mathit x2 2mathit x 8 42x22x 8. Find the value of five to the third power let me rewrite that we have five to the third power now its important to remember this does not mean five times three this means five times itself three times so this is equal to five times five times five five times three just as a bit of a refresher so you realize the difference five times three to let me write it over here five times three five.
You can put this solution on YOUR website. Tap for more steps. Solve the linear equation as you normally would.
Start by factoring the base values to get a common base for the exponents. Check 3 4 8 7 8. The equation calculator allows you to take a simple or complex equation and solve by best method possible.
