3a+b²=3(3)+5²=34
therefore 34 is the answer
3 a + b 2 = 3 ⋅ 3 + 5 2 = 9 + 25 = 34
By substituting the values a = 3 and b = 5 into the expression 3 a + b 2 , we find that the value is 34 . This is achieved through calculations of b 2 and 3 a separately before summing them. Thus, the final answer is 34 .
