Question

If a * b = a² + b², then the value of (4 * 5) * 3 is _____________ .

विकल्प

• (4² + 5²) + 3²

• (4 + 5)² + 3²

• 41² + 3²

• (4 + 5 + 3)²

Answer 1

\[\left( {41}^2 + 3^2 \right)\] 

Given: a * b = a² + b²

\[\left( 4 * 5 \right) * 3 = \left( 4^2 + 5^2 \right) * 3\]
                  \[ = \left( 4^2 + 5^2 \right)^2 + 3^2 \]
                   \[ = {41}^2 + 3^2\]
