Materi : Bentuk Akar dan Pangkat, SPLSV
( x - 5 )⁵( x + 4 )⁵ = ( x - 2 )¹⁰
( x² - x - 20 )⁵ = ( x - 2 )¹⁰
x² - x - 20 = ⁵√( x - 2 )¹⁰
x² - x - 20 = ( x - 2 )²
x² - x - 20 = x² - 4x + 4
- x - 20 = - 4x + 4
4x - x = 20 + 4
3x = 24
x = 8
Semoga bisa membantu

Penyelesaian
(x-5)⁵(x+4)⁵=(x-2)¹⁰
((x-5)(x+4))⁵=(x-2)¹⁰
(x-5)(x+4)=(x-2)^10/5
x²-5x+4x-20=(x-2)²
x²-x-20=x²-4x+4
-x-20=-4x+4
-x+4x=4+20
3x=24
Jadi x=24/3=8
Semoga bermanfaat
