Answer 1

Answer:

{3^(3x+1) +19}/10=3^2+1^2

Or, {3^(3x+1) +19}=10*(3^2+1^2)

or, {3^(3x+1) +19}=10*3^2+10

or, 3^(3x+1)=10*9+10-19=90-9

or, 3^(3x+1)=81

Or, 3^(3x+1)=3*3*3*3

or, 3^(3x+1)=3^3________________________(1)

from the equation (1) we get,

3x+1=3

or, 3x=3-3=2

Or, x=(2/3)

answer is x=(2/3)
