Question

Help pls i don't understand

Answer 1

Option B

Explanation:

`6^(2) = 36`

`√(81) = 9`

Substitute the above two values in each of the four expressions and solve using BODMAS and Distributive Law:

A.
`(36 + 2) - 8(9)`

=
`(18) -(72)`

=
`18 - 72`

=
`-54` ≠
`-18`

C.
`(36 + 2 - 8)(9)`

=
`(30)(9)`

=
`270` ≠
`-18`

D.
`36 + 2 - [(8)(9)]`

=
`36 + 2 - 72`

=
`-34` ≠
`-18`

B.
`36 + (2-8)(9)`

=
`36 + (-6)(9)`

=
`36 -54`

=
`-18` ≡
`-18`

∴Option B
