Question

4) Evaluate the expression $$ 3 a+4 b^{3}-5 $$ when $$ a=6 $$ and $$ b=2 $$. $$ \begin{aligned} 3 a+4 b^{3}-5 & =3(6)+4(2)^{3}-5 \ & =	ext { ? }\end{aligned} $$

1. Substitute $$ a=6 $$ and $$ b=2 $$ into the expression:
   $$
   3(6) + 4(2)^3 - 5
   $$

2. Calculate the exponent:
   $$
   (2)^3 = 8
   $$

3. Substitute the value back into the expression:
   $$
   3(6) + 4(8) - 5
   $$

4. Multiply:
   $$
   18 + 32 - 5
   $$

5. Add and subtract:
   $$
   50 - 5 = 45
   $$

Thus, the value of the expression is $$ 45 $$.
The value of the expression is 45.
