$\overline{abcd}=A$(four digital nmber) is a perfect square ,given $\overline{ab}=2\overline{cd}+1$
find $A=?$
find $A=?$
The formula for finding a perfect square in the given equation is ab=2cd+1, where a and b are two digits and c and d are consecutive digits.
You can determine if the given number is a perfect square by solving the equation ab=2cd+1 and checking if the resulting value of a is a perfect square number.
Yes, you can use any four-digit number for this equation. However, the number must follow the format of abcd, where a and b are two digits and c and d are consecutive digits.
The possible values for a, b, c, and d in this equation are integers, where a and b are two digits and c and d are consecutive digits. Additionally, a and b must satisfy the equation ab=2cd+1.
No, this equation is specifically for finding perfect squares in four-digit numbers. For numbers with a different number of digits, a different equation or method would need to be used.
