A stable nucleus

C

is formed from two radioactive nuclei

A

and

B

with decay constants

\lambda_1

and

\lambda_2

, respectively. Initially, the number of nuclei of

A

N_0

and that of

B

is zero. Nuclei

B

are also produced at a constant rate

P

. Find the number of nuclei of

C

after time
