jika x memenuhi 3x⁰’⁴-9(1/3)⁰'⁶= 0,maka 3x-x2 sama dengan
Jawaban:
0
Penjelasan dengan langkah-langkah:
[tex] {3x}^{0.4} - 9( \frac{1}{3} ) {}^{0.6} = 0[/tex]
[tex]3 {x}^{0.4} - {3}^{2} .( {3}^{ - 1} ) {}^{0.6} = 0[/tex]
[tex] {3x}^{0.4} - 3 {}^{2 - 0.6} = 0[/tex]
[tex] {3x}^{0.4} = {3}^{1.4} [/tex]
[tex] {x}^{0.4} = \frac{ {3}^{1.4} }{3} [/tex]
[tex] {x}^{0.4} = {3}^{0.4} [/tex]
[tex]x = 3[/tex]
[tex]3x - {x}^{2} = 3.3 - {3}^{2} = 0[/tex]
