1. Note that 4^x.3^x= 12^x
So the integral is M= ∫12^xdx
Substitute y=12^x so that dy=12^x.ln12 dx
So M= ∫dy/ln12
= y/ln12
= 12^x/ln12
2. Number of numbers that are multiples of 2 or 5=
Number of multiples of 2 + number of multiples of 5 - number of multiples of 10 
= 30 + 12 - 6
= 36
Hence probability= 36/60
= 3/5
KINDLY APPROVE :))
