what is the value of n to make 16^41+2^7925+16^n a perfect square

Reply Like? Yes | No

MOKBUL SK 6 years ago

= 2^(4*41) +2^7925 +2^(4*n)
= 2^(164) + 2^7925 + 2^(4*n)
compare it with a^2 +2ab+b^2
= (2^82)^2 + 2*2^82 * 2^2*n + (2^2*n)^2
so, 2*2^82 * 2^2*n =2^7925
or, 2^82 * 2^2*n =2^7924
or, 2^(82+2n) =2^7924
or, 82+2n =7924
or, 2n =7842
or, n =3921.

Suppose present ages of x and y are X and Y respectively.
when x was Y years old [( X-Y) years earlier), y was [Y-(X-Y)] i.e. 2Y-X years old.

As per goven statement, X= 5(2Y-X)
Then 6X=10Y
