Rozwiąż równania a) x^(4/7) - 8*x^(2/7) = 0 b) ³√x -8* ³√(x²) = 0

a) x^(4/7) - 8*x^(2/7) = 0 x^(4/7)=8*x^(2/7)/:√(x^(2/7)) x^(2/7)=8 x=8^(7/2) b) ³√x -8* ³√(x²) = 0 ³√x=8³√(x²) /:√(x²) ³√x=1/8 x=1/512

a) x^(4/7) - 8*x^(2/7) = 0 x^(4/7) = 8x^(2/7) x^(2/7) = 8 x = 8^(7/2) b) ³√x -8* ³√(x²) = 0 ³√x = 8* ³√(x²) x^(1/3) = 8* x^(2/3) 1 = 8 * ³√x 1/8 = ³√x x=1/512
