The value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The expression is:
= 13(a×b + a²) + 4
Plug a = 5
b = -3
= 13(5×(-3) + 5a²) + 4
= 13(-15 + 5(25)) + 4
= 13(-15 + 125) + 4
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
= 13(110) + 4
= 1430 + 4
= 1434
Thus, the value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.
