**View question 3^x=1/81 solve for x**

2008-03-25 · There's two things you could do. Log(base a)n = x is the same as a^x = n. so 3^x = 243 so x = 5 because I'm sure 3^5 = 243. A log is basically the power the base needs to be raised to, to equal the number of which you're taking the log to that base.... 2012-02-25 · There's 2 ways to do it. 1.The first way is simpler, but only works if you can see it. You need to make the bases the same, then simplify and rearrange.

**Solve 3^(4x+1) 2*3^(2x+2) = 81**

Example: Solve 3 x - 1 = 81. Solution: 3 x - 1 = 81 3 x - 1 = 3 4 x - 1 = 4 => x = 5. Example: Solve 0.25 x = 4 3x - 2.... To solve this you need to have the same base. 81 is the fourth root of 3 so 3^2x = 3^4. Then, you just take out the bases and write an equation for the exponents. 2x = 4. Finally, divide by two and your answer is x …

**Solve for x. (x + 3)^4/3 = 81 Science Mathematics**

put 3^2(x+1)= y and then solve you wil get y^2-54y-2187=0 factorise and you will get y as 81 and -27 discard -27 as the 3^2(x+1) cannot be -ve. equate how to tell if firm is experiencing diminishing marginal product The coefficient of x 2 is -2 times that of x 3, and the same relationship exists between the coefficients of the third and fourth terms. Group terms one and two, and also terms three and four. Group terms one and two, and also terms three and four.

- What are the factors of the polynomial function P(x) = x4 – 18x2 + 81? FACTORS: (x - 3)2 and (x + 3)2 Because the same factor(s) occur more than once, the polynomial is said to have
- e x = x 3 This has two solutions: x = 4.5364... and x = 1.85718... Plot the graph of each and you can see the intersections.
- The coefficient of x 2 is -2 times that of x 3, and the same relationship exists between the coefficients of the third and fourth terms. Group terms one and two, and also terms three and four. Group terms one and two, and also terms three and four.
- For example: 2 x = 2 3, therefor x = 3. This is true because the exponential function is one-to-one. That is, for every input there is only one output.
