First we need to calculate the product, then we calculate the sum.

The product of 3 * 4 is 12.

Then we have 6 + 12, and that is equal 18.

2.

The first step to solve this question is to calculate the operations inside the parenthesis.

So the first expression is:

[tex](6+3)=9[/tex]

Then, the second expression is:

[tex](4-5)=-1[/tex]

Now, we can divide the first result by the second:

[tex]\frac{(6+3)}{(4-5)}=\frac{9}{-1}=-9[/tex]

So the value of the expression is -9.

3.

First we need to calculate the exponencial expression, then the product, and finally the sum.

The exponencial expression is:

[tex]2^3=2\cdot2\cdot2=8[/tex]

Then, the product of this value and 3 is:

[tex]2^3\cdot3=8\cdot3=24[/tex]

Finally, calculating the sum, we have:

[tex]6+2^3\cdot3=6+24=30[/tex]

So the result is 30.
