" 8."(1-i)^(4)quad " 9."

If 2a+b+3c=1 and a>0,b>0,c>0 then the greatest value of a^(4)b^(2)c^(2) is (1)/(9.4^(8)) b.(1)/(9.4^(5)) c.(1)/(9^(4).4^(8)) d.(1)/(9^(4).4)

Find the value of : (i) ((5)/(8))^(-1)" "(ii)((-4)/(9))^(-1)" "(iii) (-7)^(-1) " " (iv)((1)/(-3))^(-1)

If A= (1)/(9)[{:(-8,1,4),(4,4,7),(1,-8,4):}],"prove that"" "A^(-1)=A^(T).

Find a rational number between (i) (3)/(8) and (2)/(5) (ii) 1.3 and 1.4 (iii) - 1 and (1)/(2) (iv) -(3)/(4) and -(2)/(5) (v) (1)/(9) and (2)/(9)

Compare the following fractions using the symbol >or (i) 8/3 and 8/(13) (ii) 4/9 and (15)/8

Show that 9^(1/(4)).9^(1/(8)).9^(1/(16).) . .."to" oo = 3

Show that 9^(1/(4)).9^(1/(8)).9^(1/(16).) . .."to" oo = 2

If I_(n)=int_(0)^((pi)/(4))tan^(n)xdx, where n is a positive integer,then I_(10)+I_(8) is equal to (A)(1)/(9)(B)(1)/(8) (C) (1)/(7)(D)9
