Key concept: If x>0, then √x=x12
So, we can rewrite Quantity A as follows:
QUANTITY A: (m12)12
QUANTITY B: (m2)5
Apply the power of a power law to both quantities to get:
QUANTITY A: m6
QUANTITY B: m10
Since m>1, we can be certain that Quantity B is greater.

Option A = sq m^12 = m ^ 12/2 = m^6
Option B = (m^2)^5 = m ^ 2*5 = m^ 10
Since m>1, option B > A, hence the correct ans
Option B = (m^2)^5 = m ^ 2*5 = m^ 10
Since m>1, option B > A, hence the correct ans
