Find the cofficient of xyz in xyz

Find the number of terms in 4xyz-(3)/(x^(2))+6xyz^(2)-5z^(3)+6x:

Find each of the following products -(4)/(27)xyz ((9)/(2)x^(2)yz - (3)/(4)xyz^(2))

In Figure,/_X=62^(0),/_XYZ=54^(@)* If YO and ZO are bisectors of /_XYZ and /_XZY respectively of XYZ find /_OZY and /_YOZ

Evaluate (1)/(log_(xy)(xyz))+(1)/(log_(yz)(xyz))+(1)/(log_(zx)(xyz))

Evaluate : (xyz)([a,h,gh,b,fg,f,c])([xyz])
