If `a` and `b` be positive integers such that `a^2-b^2=19 ,` then the value of `a` is 9 (b) 10 (c) 19 (d) 20

If a and b are positive integer and a^2 - b^2 = 9 xx 11 then lets write the value of a & b

If a a n d b are positive integers, a > b and (a+b)^2-(a-b)^2> 29 , then the smallest value of a is 3 (b) 4 (c) 6 (d) 7

If a,b,c are consecutive positive integers and (log(1+ac)=2K, then the value of K is log b(b)log a(c)2(d)1

Let a , b , c , d be positive integers such that (log)_a b=3/2a n d(log)_c d=5/4dot If (a-c)=9, then find the value of (b-d)dot

Let a , b , c , d be positive integers such that (log)_a b=3/2a n d(log)_c d=5/4dot If (a-c)=9, then find the value of (b-d)dot

Let a , b , c , d be positive integers such that (log)_a b=3/2a n d(log)_c d=5/4dot If (a-c)=9, then find the value of (b-d)dot

Let a,b,c,d be positive integers such that log_(a)b=(3)/(2) and log_(c)d=(5)/(4). If (a-c)=9, then find the value of (b-d)

Let a, b, c, d be positive integers such that log_(a) b = 3//2 and log_(c) d = 5//4 . If (a-c) = 9, then find the value of (b-d).

Let x+y=1 and x^(3)+y^(3)=19, then the value of x^(2)+y^(2) is equal to 9(b)19(c)39(d)13
