Question

If 1×4 = 2 2 × 4=8 3×16=36 4×9=48 then 5×36 =?

Answer 1

Answer:

1×4=4 and √4=2than 1×2=2and 4-2=2

2×4=8 , √4 =2 , 2×2=4 and 8+4=12 Ans is 12 not 8

3×16=48 ,√16= 4 , 3×4=12 , 48-12=36

4×9=36, √9=3 , 4×3=12 , 36+12=48

1st step is subtract , second plus , 3rd subtract , 4rd plus and so on

5×36=180 , √36=6 , 6×5 =30 , this step again subtract 180 -30=150
