Method 1 :
Rate = k [A] [B]³
When [A] = a and [B] = b: Rate = R
R = k a b³
When [A] = 2a and [B] = 3b:
Rate = k (2a) (3b)³ = 54 k a b³ = 54 R
The rate increases 54 times.

Method 2 :
Times that the rate increases = 2 × 3³ = 54
Rate = k [A] [B]³
When [A] = a and [B] = b: Rate = R
R = k a b³
When [A] = 2a and [B] = 3b:
Rate = k (2a) (3b)³ = 54 k a b³ = 54 R
The rate increases 54 times.
