(1+ tan1)(1+tan2)...........(1+tan45)=2^y
y=?????
TAN45=1=TAN(1+44)
1=(TAN1+TAN44)/(1-TAN1TAN44)
1=TAN1+TAN44+TAN1TAN44
2=1+TAN1+TAN44+TAN1TAN44
I.E
2=(1+TAN1)(1+TAN44)
SIMILARLY
2=(1+TAN2)(1+TAN43)
.................................
................................
2=(1+TAN22)(1+TAN23)
MULTYPLING WE GET
(1+TAN1)(1+TAN2)...........(1+TAN44)=2^22
MULTIPLYING BY (1+TAN45)=2 we get
the question which is equaal to 2^23
so y=23
hope you like the answer
