To determine if ( b^2(c + d) ) is rational, we need to know the values of ( b ), ( c ), and ( d ). If ( b ), ( c ), and ( d ) are all rational numbers, then ( b^2 ) is rational (since the square of a rational number is rational) and ( c + d ) is also rational (as the sum of two rational numbers is rational). Therefore, the product ( b^2(c + d) ) would be rational as well. However, if any of these values are irrational, then ( b^2(c + d) ) may not be rational.
