" 6.If "2^(n-7)times5^(n-4)=1250," find the value of "n" ."

If 2^(n-7) xx 5^(n-4)=1250, find the value of n.

If 2^(n-7) xx 5^(n-4)=1250, find the value of n. Hint: 2^(n-4) xx 2^(-3) xx 5^(n-1)=1250 implies frac(2^(n-4) xx 5^(n-4))(2^(3))= 1250 implies (2 xx 5)^(n-4)=(10)^(4).

If .^(n)P_(4): .^(n)P_(5) = 1:2 , find the value of n.

If .^(n)P_(4): .^(n)P_(5) = 1:2 , find the value of n.
