Answer:
[tex]17[/tex]
Step-by-step explanation:
[tex]9+3*2^2-1*4[/tex]
We use PEMDAS to determine what order to do things
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
First we do the exponent
[tex]9+3*4-1*4[/tex]
Next we multiply
[tex]9+12-1*4[/tex]
[tex]9+12-4[/tex]
Now we add
[tex]21-4[/tex]
And finally we subtract
[tex]17[/tex]
I hope this helps
