[tex]\displaystyle\bf~ \frac{ {x}^{9} - {x}^{5} }{ {x}^{5} } = 15[/tex]

tentukan nilai x.​

Answer 1

Jawaban:

Bilangan Berpangkat

Penjelasan dengan langkah-langkah:

x⁹ - x⁵ = 15

x⁵

x⁹/x⁵ - x⁵/x⁵ = 15

x⁹⁻⁵ - x⁵⁻⁵ = 15

x⁴ - x⁰ = 15

x⁴ - 1 = 15

x⁴ = 15+1

x⁴ = 16

x⁴ = 2⁴

x = +-2

x = 2 atau x=-2

Demikian

Answer 2

Jawaban:

aljabar

[tex] \frac{ {x}^{9} - {x}^{5} }{x {}^{5} } = 15 \\ \frac{ {x}^{5} ( {x}^{4} - 1)}{ {x}^{5} } = 15 \\ {x}^{4} - 1 = 15 \\ {x}^{4} = 16 \\ {x}^{} = \pm \sqrt[4]{16} \\ x = \pm2[/tex]
