`(19^(@)-(-9)^(@))/(((-3)/(4))^(@))`

Let S=(4)/(19)+(44)/((19)^(2))+(444)/((19)^(3))+...oo then find the value of S

The value of (19^(3)+6^(3)+(3)(19)(6)(25))/(3^(6)+6(243)(2)+(15)(81)(4)+(20)(27)(8)+(15)(9)(16)+(6)(3)(32)+2^(6)) is

If S = (7)/(5) + (9)/(5^(2)) + (13)/(5^(3)) + (19)/(5^(4)) + …., then 160 S is equal to ________ .

{(1/3)^(-3)-(1/2)^(-3)}-:(1/4)^(-3) = (a) (19)/(64) (b) (64)/(19) (c) (27)/(16) (d) (-19)/(64)

{(1/3)^(-3)-(1/2)^(-3)}-:(1/4)^(-3) = (19)/(64) (b) (64)/(19) (27)/(16) (d) (-19)/(64)

Simplify and write the following in the exponential form: (i) ((-3)^(5)xx4^(6)xx4)/((-3)^(2)xx4^(9)) (ii) (11^(4)xx17^(3)xx19^(5))/(11^(2)xx17^(2)xx19^(2))

(16(2)/(5)-12(1)/(15))-:3(4)/(81)=?( a) 1(9)/(19) (b) 1(9)/(13)(c)2(8)/(13) (d) 3(2)/(19) (e) None of these

The image of the point (-1,3,4) in the plane x-2y=0 is a.(-(17)/(3),-(19)/(3),4) b.(15,11,4) c.(-(17)/(3),-(19)/(3),1) d.((9)/(5),(-13)/(5),4)
