" Show that "(1+3^(-1))(1+3^(-2))(1+3^(-4))(1+3^(-8))...(1+3^(-2))=

Prove that (1-1/3+1/3^(2)-1/3^(3)+1/3^(4)-...oo)=3/4

(1)/(3)+(1)/(2.3^(2))+(1)/(3.3^(3))+(1)/(4.3^(4))+….oo=

Show that 1+(1+3)/(2!)+(1+3+3^2)/(3!)+...=1/2(e^3-e)

Find (1)/(3)+(1)/(2.3^(2))+(1)/(3.3^(3))+(1)/(4.3^(4))+….oo=?

If A=[(2,-1),(-1,2)] , then show that A^(-1) =[((2)/(3),(1)/(3)),((1)/(3),(2)/(3))]

1+(3+1)(3^(2)+1)(3^(4)+1)(3^(8)+1)(3^(16)+1)(3^(32)+1) is equal to (3^(64)-1)/(2) b.(3^(64)+1)/(2) c.3^(64)-1 d.3^(64)+1

(4^(-1)-3^(-1))^(-1)+(2^(-1)-3^(-1))^(-1)=((1)/(4)-(1)/(3))^(-1)+((1)/(2)-(1)/(3))^(-1)

{(1/3)^2}^4 is equal to (a) (1/3)^6 (b) (1/3)^8 (c) (1/3)^(24) (d) (1/3)^(16)
