Q.1)   Solve.

1)  If 2x = 23y =512 find the value of log x3 where z =y3.(page no. 8) 

2)    If log10 2 = 0.3010 find log10 8.(page no. 21)

3)    Prove that log (log x7)-log (log x 3) = log (7/3)(page no. 16)

            4)   Simplify   log 2 14 - log 2 7(page no. 7)

5)  (page no. 12)

Q.2)   Solve.

1)  Solve                      (page no. 26)

2)  Solve                      (page no. 28)

4)    Find the value of K for which the following equations are consistent

                                                                                                 (page no. 57)

                                x – 2y = 7

                              kx + y = 7

                              2x – 3y = 12

4)  Solve given determinant and find the value of x (page no. 41)

                

 

5)  Find out the following equations are Consistant or not(page no.54)         

                x – 2y – 3 = 0

               3x + 4y + 1 = 0

               2x + 7y + 5 = 0
