Best ResponseYou've already chosen the best response.0\[5^{(x+1)}(13) = 22 =>5^{(x+1)} = 11 =>x is imaginary\]

Best ResponseYou've already chosen the best response.0you can write \[5^{x+1}=5^2\times 5^{x1}\] and the solve \[25\times 5^{x1}3\times f^{x1}=22\] \[22\times 5^{x1}=22\] \[5^{x1}=1\] \[x1=0\] \[x=1\]

Best ResponseYou've already chosen the best response.0Another version: \[5^{x+1}  3\cdot5^{x1} = 22\] \[5\cdot 5^x\frac{3}{5}5^x=22\] \[25\cdot 5^x3\cdot 5^x=110\] \[22\cdot 5^x=110\] \[5^x=5\] \[x=1\]
