Algebra -> Numeric Fractions Calculators, Lesson and Practice -> SOLUTION: what is 4/9 X 27? I don't agree with my Grandson's answer of 12. I don't agree with my Grandson's answer of 12. …

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 …

27^x = 9^(x+2) becomes 27^4 = 9^6 which becomes 531441 = 531441 this confirms the solution is good. ...

9^x=27 3^2x=3^3 2x=3 x=3/2 . Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR ...

You can put this solution on YOUR website! 9^(x)=27 ----Convert both sides to the same base. (3^2)^x = 3^3-----3^(2x) = 3^3

Now, we will combine like terms on the left hand side: Notice that to combine the (-1/9)x and (1/3)x we have to transform 1/3 into 3/9 so that we have a common denominator. So, Now, …

We shouldn't use logarithms if we can avoid it. 9 x = 6561 We recognize 9 as 3 2 Perhaps 6561 is also a power of 3. Let's find out: 6561/3 = 2187 2187/3 = 729 729/3 = 243 243/3 = 81 81/3 = …

9 * x - 20 = 7 add 20 to both sides of that equation to get 9 * x = 27 divide both sides of that equation by 9 to get x = 27/9 = 3 the number is 3. go back to the original statement and see if …
