`1+1/4+1/4 3/8 + 1/4 3/8 5/12 + .....+ oo`

1.Draw number lines and locate the points on them: (a) 1/2, 1/4, 3/4, 4/4 (b) 1/8, 2/8, 3/8, 7/8 (c) 2/5, 3/5, 8/5, 4/5

2^(1/4). 4^(1/16). 8^(1/48) .........oo =

The value of 3 1/5 div 4 1/2 of 5 1/3+1/8 div 1/2 of 1/4-1/4(1/2 div 1/8xx1/4) is: 3 1/5 div 4 1/2 of 5 1/3+1/8 div 1/2 of 1/4-1/4(1/2 div 1/8xx1/4) का मान क्या होगा:

The value of 1 1/8 div (4 1/4 div 3/5 of 8 1/2)-2/5xx1 1/3 div 4/5 of 1 2/3+11/20 is:- 1 1/8 div (4 1/4 div 3/5 of 8 1/2)-2/5xx1 1/3 div 4/5 of 1 2/3+11/20 का मान होगा ?

It is given that (1)/( 1^(4) ) + ( 1)/( 2^(4)) + ( 1)/( 3^(4)) +"......" to oo = ( pi^(4))/( 90) , then (1)/( 1^(4)) +( 1)/( 3^(4)) +( 1)/( 5^(4)) + "......" to oo is :

The sum of 1+1/4+(1.3)/(4.8)+(1.3.5)/(4.8.12)+.........oo is

Show that + 1/4 + (1.3)/(4.8) + (1.3.5)/(4.8.12) + …….= sqrt2
