Question

Fill in the blank

$\begin{array}{ccc}6& 4& \left(100\right)\\ 8& 5& \left(189\right)\\ 11& 3& (-)\end{array}$

Answer 1

The third number in each row is the sum of the square of the first number and the cube of the second number.
$a^2+b^2=c$
$6^2+4^2=36+64=100$
${11}^2+5^2=64+125=189$
${11}^2+3^2=121+27=148$
