Calculate the values of x if
@ganeshie8

Answer 1

\[3^{2x+1}-3^{x+2}=3^{x+3}-3^4\]

Answer 2

let \(t=3^x\) and make a quadratic in terms of \(t\)

Answer 3

\[t(3^3)-t(3^2)-t(3^3)=-3^4\]

Answer 4

\[t(3^3-3^2-3^3)=-3^4\]\[t(9)=81\]

Answer 5

\[t=9\]

Answer 6

\[x=2\]

Answer 7

Like this? @mukushla

Answer 8

except that\[3^{2x+1}=3t^2\]

Answer 9

\[3t^2-9t-27t+81=0\]

Answer 10

\[3t^2-36t+81=0\]

Answer 11

\[3(t^2-12t+27)=0\]

Answer 12

\[t=3,t=9\]

Answer 13

\[3^x=3^1,3^x=3^2\]

Answer 14

\[x=1,x=2\]
