**How to solve for "x" when it's raised to a power? Yahoo**

Solving the equation x 2 = y for x by using the square root function Suppose that x is unknown but that x 2 equals a known value y. Then finding x requires solving the following equation for x. x 2 = y There are two solutions. One solution is This is because means the number which when squared would produce y. But the original equation says that this number is x. There is a second solution... 20/11/2008 · so x^2 = 9, so x = (+-) 3. Since a quartic strictly speaking has four solutions; each of these last two is duplicated twice, so that we have 2 equal roots at x = 3 and two equal roots at x = -3. Dr Octavian · 1 decade ago

**How do you solve a number to a negative power?**

We can use logarithms to solve *any* exponential equation of the form a⋅bᶜˣ=d. For example, this is how you can solve 3⋅10²ˣ=7: 1. Divide by 3: 10²ˣ=7/3 2. Use the definition of logarithm: 2x=log(7/3) 3. Divide by 2: x=log(7/3)/2 Now you can use a calculator to find the solution of the equation as a rounded decimal number We can use logarithms to solve … how to start a gas powered lawn mower 9/04/2003 · the full solution of the quartic equation is fairly long. so rather than retyping a lot of calculations, i will link you to a solution here

## How To Solve When X Is A Power

Note that C3 will show the solution of the formula for when x= 10 or = 2*10^7* 10 ^-2.146 = 142,899.277 Using Goal Seek To use Goal Seek to find what value of x ( B3 ) will result in y ( C3 ) = 60,

- In your algebra classes, you will often have to solve equations with exponents. Sometimes, you may even have double exponents, in which an exponent is raised to another exponential power, as in the expression (x^a)^b.
- The easiest way to solve negative powers is by writing it all out. You already know that positive powers (regular exponents) turn from something like 3 3 to 3 X 3 X 3 to e … qual 9 X 3, or 27.

- The Exp (x) function is used to determine e raised to the power of x. If you want to solve e x =5, you need to take the natural log of both sides. where e is the number also called as Napier's Number and its approximate value is 2.718281828.
