If $a^ 2 + b^ 2 + 1 = 2a$, then the value of $a^4+b^7$ is:
Answer & explanation
Correct answer: option 1
If $a^ 2 + b^ 2 + 1 = 2a$
$a^4+b^7$ = ?
Put the value of a = 1 and b = 0
These values will satisfy the equation.
$a^4+b^7$ = $1^4+0^7$ = 1
If $a^ 2 + b^ 2 + 1 = 2a$, then the value of $a^4+b^7$ is:
