Answer:
Answer- 50
Step-by-step explanation:
√mn=10
√100=10
if m=20 then n=5so20+5=25
if m=50 then n=2so50+2=52
if m=100 then n=1so 100+1=101
Hence 50 is the answer

Answer:
correct answer is 50
Step-by-step explanation:
case (i) let m= 100 , n= 1
√mn = √100×1= √100 = 10
m+n = 101
case(ii) let m=50, n=2
√mn = √50×2= √100 = 10
m+n= 52
case(iii) let m= 20, n= 5
√mn = √20×5= √100 = 10
m+n = 25
so only 50 is not possible
