Question

If m^2=5m-3 ,n^2=5n-3 and m not equal n then what is value of mn?

Answer 1

Answer:

m=5,n=1

Step-by-step explanation:

a^1/a^2=b^1/b^2=c^1/c^2

3/m+n=4/2(m-n)=12/5m-1

3/m+n=2m-n=12/5m-1

3/m+n=2/m-n

=3(m-n)=2(m+n)

=3m-3n=2m+2n

=m=5n-1

2/m-n=12/5m-1

2/5n-n =12/5(5n)-1

2/4n=12/25n-1

1/2n=12/25n-1

25n-1=24n

from 1 and 2

m=5

n=1
