Short Answer

Expert verified

The value of the expression is $鈭� 18$ .

Step by step solution

– Write the given information

The expression given is

$a 鈭� b + 5 a 鈭� 2 b$

And

$a = 鈭� 1, b = 4 and c = 6$

- DESCRIPTION OF STEP

To solve the given expression substitute variables a, and b by $- 1$ , and 4 respectively, as:

$\begin{matrix} a 鈭� b + 5 a 鈭� 2 b = 鈭� 1 鈭� 4 + 5 (鈭� 1) 鈭� 2 (4) \\ = 鈭� 5 鈭� 5 鈭� 8 \\ = 鈭� 18 \end{matrix}$

Thus, $a 鈭� b + 5 a 鈭� 2 b = 鈭� 18$ .
