Question

Tolong yaa sama caranya, makasih

Answer 1

16) 6^x+2 = (36)^x+2
6^x+2 = (6²)^x+2
=> x + 2 = 2(x + 2)
=> x + 2 = 2x + 4
=> x - 2x = 4 - 2
=> - x = 2
=> x = - 2

17)4^x+3 = ⁴√16^x+5
4^x+3 = ⁴√(4²)^x+5
=> x + 3 = 2(x + 5) / 4
=> 4(x + 3) = 2x + 10
=> 4x + 12 = 2x + 10
=> 4x - 2x = 10 - 12
=> 2x = - 2
=> x = - 1

18) 6^x+2 = (36)^x+2
6^x+2 = (6²)^x+2
=> x + 2 = 2(x + 2)
=> x + 2 = 2x + 4
=> x - 2x = 4 - 2
=> - x = 2
=> x = - 2
