What's


( where, x = 12 and y = 11 )​

here's your solution

=> we need to solve this ( x^2 -y^2)

=> it is given that x = 12 y= 11

=> now putting the value of these in question

=>. 12^2 - 11^2

=> 144 - 121

=. 23

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
