Question

f varies jointly as g2 and h, and f = 50 when g = 4 and h = 2. Find when g = 3 and h = 6

Answer 1

is this correct guys?

F=k•g²•h
50=k(4) ² • 2
50=k•32
K= 50/32 divided by 2

K= 25/16


F= 25/16• (3) ² 6

F= 25/16 • 54/1

F= 1350/16

F= 84.375

Answer 2

Nice, that's the way I would do it,
