If q=(L x K) to the power of 1/2 given Q= 50 how do i find the different combinations which can equal to L and K to give me Q=50 For example if L=125 and K= 20 i would get Q=50 how do i work out the different combinations with only given Q=50.

If Q = (L*K) power 1/2 ; Q = 50 Then L*K = 2500 So we need to find the factors of 2500. The possible chances are : 1*2500, 2*1250, 4*625, 5*500, 10*250, 20*125, 50*100 and their reciprocals. As L and K are two different characters, the reciprocals also will be counted and hence the answer is "The different combinations are 14" Hope this helps!
