Answer: The value of
is 36.
Step-by-step explanation:
Given expression: 
To find the value of
at b= 5, we need to substitute the b=5 in the expression, we get
![6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36](https://tex.z-dn.net/?f=6%282%285%29-4%29%5C%5C%3D6%2810-4%29.......%5B%5Ctext%7Bsolve%20parentheses%7D%5D%5C%5C%3D6%286%29%5C%5C%3D6%5Ctimes6%3D36)

Therefore, the value of
is 36, when b=5.
