64.

ReplyDeleteEach number alone in its row is the product of (the square root of the first number of the row above) and (the second number of the row above).

Thus:

sqrt(81)*6=9*6=54

sqrt(144)*7=12*7=84

sqrt(64)*8=8*8=64

That's right. The answer is 64. You figured out the pattern fairly quickly!

ReplyDeletethe answer is 64.. please dont overact.. !!
