espressioni di monomi

a)

a/b = c 

b = a/c = 16*x^2*y^2/(2*x*y) = 8xy

 

b)

a/b = c 

b = a/c =x^3/3*y*z^2*-3x^2y^2 = -x^5*y^3*z^2

 

c)

a/b = c 

a = b*c = 2/5*a^3*b*c^2*3/4*b^2*c = 3/10*a^3*b^3*c^2

 

d)

a/b = c 

a = b*c = 2/5*a^3*b*c^2*3/4*b^2*c = 3/10*a^3*b^3*c^2

 

e)

b = c/a = -3/2*a^2*b^2 /(5/2*a*2*b) = -3/5b 

 

f)

b= a/c

12 = k*-4 ; k = -3

-3*x^3y^2*-4/(x*y) = 12*x^2*y
