x(x+1) is WRONG! It means a function x of x-1. x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means Resources: Simplifier Portal, help with entering simplifier formulas (a must read).

Solve for x: Substitute Multiply the exponents on the left side. Invert the right side and change the sign of the exponent. Now since the bases (3) are equal, the exponents must be equal, so... Add 2x to both sides. Add 2 to both sides. Divide both sides by 4. Simplify.

Now we solve for x. Adding 3x to each side we get: 5x = -6 Dividing by 5 we get: If we are clever enough to see that 9 is a power of 1/27 (and vice versa) then the solution is a little faster becauae we only have to replace one base. For example if we replace 1/27 with we get: which simplifies to Setting the exponents of 0 equal we get: Solving ...

the original equation is log(x-2) + log(9-x) 1 in order for the expression inside the log to be greater than 0, then x has to be greater than 2 and x has to be smaller than 9. now you have 4 requirements. they are: x > 2 x 9 x 4 x > 7 this puts x in the following ranges. x > 2 and x 4 x > 7 and x 9 that would be your answer.

Question 803297: If 9^x-1 = 7 then what is 3^2x+3 The ^'s mean exponent and the 2x+3 at the end is ALL part of the exponent of 3. So it should belike 3 TO THE POWER OF "2x+3" Answer by josgarithmetic(39583) (Show Source):

You can put this solution on YOUR website! 9^X = 1/243 Take log9 (log base 9) of both sides: X = log9(1/243) X = log9(1) - log9(243)
