Answer:
x = 1
Step-by-step explanation:
Power of exponents( Formula used):
(I) a^m × b^m = (ab)^m
(II) a^m × a^n = a^(m+n)
or, 2^(x+4) × 3^(x+1) = 288
or, 2^x × 2⁴ × 3^x × 3¹ = 288
or, 2^x × 16 ^ 3^x × 3 = 288
or, 2^x × 3^x = 288/ 16× 3
or, (2 × 3)^x = 96/ 16
or, 6^x = 6
or, 6^x = 6¹ ......................(1)
As the base are same, thus the powers must be same .
or, x = 1 Ans
