Question

Which expression is equivalent to 4+[4(5-2)]÷2?A) 4+18÷2B) 8(3)÷2C) 4+12÷2

Answer 1

The given expression is

`4+\lbrack4(5-2)\rbrack\colon2`

First, we solve the difference inside the parenthesis.

`4+\lbrack4(3)\rbrack\colon2`

Then, we solve the product inside the brackets.

`4+\lbrack12\rbrack\colon2`

Then, we solve the division

`4+6`

At last, we sum

`10`

As you can observe, the equivalent expression is C, which we've got in the second step.
