3m/4x–2m/3x = 3mx/4–2mx/3 = mx/12
3m/2x+2n/y = 3mx/2+2n/y=3mxy+4n/2y
(m+n)/x* n = (m+n)/x * n = (n*(m+n))/x
m/x*n/y = mn/xy
(-5m)/3y*8y/4m = (-40my)/3 * y/4 = -(10my^2)/3 * m = -(10m^2 y2)/3
m/y:m = m/y : 3 = 1/y
(5x (9x^2)/4y = (5x * ((9*x^2))/4)*y=5x*(9x^2)/4 =(45x^3)/4*y= (45x^3)/4*y= 45x³y/4
(8mn^2)/(9x^2 y):16mn/(12xy^2 ) = (8m*n^2)/(9*x^2*y):16*m*n/(12x〖*y〗^2 ) = (8m*n^2)/(9*x^2*y):16*m*n/(12xy^2 ) = (8m *n^2)/(3^2 x^2 y) : 16 * m * n/(12xy^2 ) = (mn^2)/(18x^2 y) * m = (m^2 n^2)/(18x^2 y)*n/12xy³ = (m2n^2)/(18x^2 y) * n/(12xy^2 ) = (m^2 n^3)/(216x^3 y^3 )
Lösungen errechnen. Bei diesen Aufgaben war das erste Ergebnis schon drinne. Ich wusste nicht so recht was ich machen soll.
(-2,1 + 0,9x) 6 = -5 (0,3x – 4,2) + 0,21 = 0
( 4x + 2) ( x – 1) = ( 2x + 2)2 = 2 * (2x + 1 * (x -1)
(8x+2)/7 – (12x -3)/5 = -1 = 12x -3/5 = (31- 44x)/35
