Question

Hitung nilai x bagi persamaan
Calculate the value of x for the equation ​

Answer 1

2

Explanation:

2⁹ ÷ (4^x) = 32^x × 32^(-1)

2⁹ ÷ 32^(-1) = 32^x × 4^x

16384 = 128^x

Kalau kamu dah belajar logaritma,

`x = log_(128)(16384) \\ x = 2`

Jika belum,

2¹⁴ = 2^(7x)

Bandingkan kuasa persamaan tersebut,

7x = 14

x = 2
