Solving the Equation (3/4)^6 x (16/9)^5 = (4/3)^x+2
This problem involves simplifying expressions with fractional exponents and solving for an unknown exponent. Here's how we can break it down:
Step 1: Simplifying the Exponents
- Rewrite (16/9) as (4/3)²: This allows us to have a common base with the right side of the equation.
- Rewrite (3/4)^6 as (4/3)^-6: This is because (a/b)^-n = (b/a)^n.
Now the equation becomes:
(4/3)^-6 x ((4/3)²)⁵ = (4/3)^x+2
Step 2: Applying Exponent Rules
- Multiply exponents with the same base: (a^m) * (a^n) = a^(m+n)
The left side of the equation simplifies to:
(4/3)^(-6+10) = (4/3)^4
Step 3: Solving for x
- Equate exponents: Since the bases are the same, we can equate the exponents.
(4/3)^4 = (4/3)^x+2
This gives us: 4 = x + 2
Step 4: Finding the Value of x
- Solve for x: Subtract 2 from both sides of the equation.
x = 2
Therefore, the solution to the equation (3/4)^6 x (16/9)^5 = (4/3)^x+2 is x = 2.
