Q. soal terlampir cepat dikerjakan

TENTUKAN HP (HIMPUNAN PENYELESAIAN)

Jawaban:

$({ \frac{1}{25} })^{x - 1} = 5 \sqrt{5} \\ ({ \frac{1}{ {5}^{2} } })^{x - 1} = 5 \times {5}^{ \frac{1}{2} } \\ {( {5}^{ - 2} )}^{x - 1} = {5}^{1 + \frac{1}{2} } \\ { {5}^{ - 2x + 2} }^{ } = {5}^{ \frac{3}{2} } \\ - 2x + 2 = \frac{3}{2} \\ 2( - 2x + 2) = 3 \\ = - 4x + 4 = 3 \\ - 4x = 3 - 4 \\ - 4x = - 1 \\ x = \frac{ - 1}{ - 4} \\ x = \frac{1}{4}$

Hp {x = -¼}

Semoga membantuu

Penjelasan dengan langkah-langkah:

(1/25)^(x - 1) = 5√5

(5^-2)^(x - 1) = 5.5^½

-2(x - 1) = (1+½)

-2x +2 = 3/2

2(-2x +2) = 3

-4x +4 = 3

-4x = 3-4

-4x = -1

x = 1/4
