Given Equation is ![\frac{3^x * 9^{x+1} }{ 3^{x-1}* 9^{x-1} } \frac{3^x * 9^{x+1} }{ 3^{x-1}* 9^{x-1} }](https://tex.z-dn.net/?f=+%5Cfrac%7B3%5Ex+%2A+9%5E%7Bx%2B1%7D+%7D%7B+3%5E%7Bx-1%7D%2A+9%5E%7Bx-1%7D+%7D+)
=![\frac{3^{x - (x - 1) * 9^{x+1} } }{ 9^{x-1} } \frac{3^{x - (x - 1) * 9^{x+1} } }{ 9^{x-1} }](https://tex.z-dn.net/?f=+%5Cfrac%7B3%5E%7Bx+-+%28x+-+1%29+%2A++9%5E%7Bx%2B1%7D++%7D+%7D%7B+9%5E%7Bx-1%7D+%7D+)
=![\frac{ 3^{1} * 9^{x+1} }{ 9^{x-1} } \frac{ 3^{1} * 9^{x+1} }{ 9^{x-1} }](https://tex.z-dn.net/?f=+%5Cfrac%7B+3%5E%7B1%7D+%2A++9%5E%7Bx%2B1%7D++%7D%7B+9%5E%7Bx-1%7D+%7D+)
=![3 * 9^{(x+1) - (x-1)} 3 * 9^{(x+1) - (x-1)}](https://tex.z-dn.net/?f=3+%2A++9%5E%7B%28x%2B1%29+-+%28x-1%29%7D+)
= 3 * 9^2
= 3 * 81
= 243.
Hope this helps!
