Answer:
[tex]\large\boxed{y=22}[/tex]
Step-by-step explanation:
In this question, we're trying to find what y equals to when a = 1 and b = 2.
This means that we would be plugging in the numbers to its appropriate variable.
You would plug 1 in a and 2 in b.
Your equation should look like this:
[tex]y=3(1)(2)+2(2)^3[/tex]
Now, we will solve:
[tex]y=3(1)(2)+2(2)^3\\\\y=3(2)+2(2)^3\\\\y=6+2(2)^3\\\\(2)^3 \,\text{is the same as}\,\, 2*2*2\\\\y=6+2(8)\\\\y=6+16\\\\y=22[/tex]
When you're done solving, you should get y = 22
This means that y = 22
I hope this helped you out.
Good luck on your academics.
Have a fantastic day!
