Explanation:

Answer 2

we will use

this rule in order of operation

P: Parenthesis

E: Exponent

M: Multiplication

D: Division

A: Addition

S: Subtraction

we are given

30+2*10....

we can simplify it

`30+2*10=30+20`

`=50`

now, we will check option and verify whether it is equal to 50

option-a:

3(2+3)

=3*5

=15

so, this is FALSE

option-b:

7(2+1)

=7*3

=21

so, this is FALSE

option-c:

6(3+7)

=6*10

=60

so, this is FALSE

option-d:

5(4+1)

=5*5

=25

so, this is FALSE
