2^(x + 2) = 98^(2 - x)
(2^x)(2²) = 98² / 98^x
2^x (98^x) = 98² / 2²
(2 x 98)^x = (98/2)²
(2 x 14 x 7)^x = 49²
(14 x 14)^x = 49²
(14²)^x = (14^x)² = 49²
14^x = 49
(2^x)(2²) = 98² / 98^x
2^x (98^x) = 98² / 2²
(2 x 98)^x = (98/2)²
(2 x 14 x 7)^x = 49²
(14 x 14)^x = 49²
(14²)^x = (14^x)² = 49²
14^x = 49
