A=[(a,1,0),(1,b,d),(1,b,c)],B=[(a,1,1),(0,d,c),(f,g,h)],U=[(f),(g),(h)],V=[(a^2),(0),(0)] If there is a vector matrix X, such that AX = U has infinitely many solutions, then prove that BX = V cannot have a unique solution. If a f d != 0. Then,prove that BX = V has no solution.

Express 0.001 as a fraction in the simplest form.

pH of a 0.001 M solution of hydrochloric acid will be

What is the logarithm of 0.0001 with respect to base 10 ?

Calculate the pH of 0.001 M HCl solution.

The pH of 0.001 M HCN is

The focal length of a less is given by the formula (1)/(f)=(1)/(u)+(1)/(v) . Make f as the subject of the formula. if u=20cm and v=30, then find f. The following steps are involved in solving the above problem. Arrange them in sequential order. (A) Given (1)/(f)=(1)/(u)+(1)/(v) (B) rArr f=(uv)/(u+v) (C) f=(20xx30)/(20+30)=(600)/(50)=12 cm. (D) rArr (1)/(f)=(v+u)/(uv)
