Answer:
Ans. : 5
Step-by-step explanation:
3^(3x+³ = 9^(x+⁴)
=) 3^(3x+³) = (3²)^(x+⁴)
=) 3^(3x+³) = 3^(2x+8)
=) 3x + 3 = 2x + 8 [∵the bases are same]

Step-by-step explanation:
(3^3)^(x+3) = 9^(x+4)
so lets make bases equal
(3)^(3x+9) = (3)^(2x +8)
now lets compare powers
3x+9 = 2x+8
3x-2x = 8-9
x = -1
so val of equation will be
3 ^( 3 (-1) +9) = 3 (2(-1)+8)
3^6 = 3^6
729 = 729 answer
