Solution:
we have been asked to simplify
(2− 1) + 3^2 ÷ 3
Using PEMDAS rule
we will simplify it in the order of PEMDAS
Parenthesis first we get
1+3^2 ÷ 3
Now does the exponent operation
1+9 ÷ 3
Now does the division Operation
1+3
Now does the addition operation
4
Hence the simplified value of the expression (2− 1) + 3^2 ÷ 3 is 4.
Hence the correct option is A

Answer:
2
Step-by-step explanation:
f(x)= 2x^5-3x^3+2x^2+1
Let x=1
f(1)= 2(1)^5-3(1)^3+2(1)^2+1
= 2*1 -3*1+2(1) +1
= 2-3+2+1
