Question

Please help with these questions a b and c pls tyyyyyyy

Answer 1

23, 5, 3

Explanation:

Following the order of operations as stated in PEMDAS , then

(a)

5 + 2 × 3² ← evaluate exponent

= 5 + 2 × 9 ← perform multiplication

= 5 + 18 ← perform addition

= 23

---------------------------------------

(b)

`(7+8)/(5-2)` ← perform calculations on numerator/denominator

=
`(15)/(3)` ← perform division

= 5

-------------------------------------------

(c)

`(18-3(2))/(5-1^2)` ← evaluate numerator/denominator using PEMDAS

=
`(18-6)/(5-1)`

=
`(12)/(4)`

= 3
