Question

Plz help I don't want to be awake the whole night

Answer 1

Therefore

`75/ 5 - [(9-7)* 3 ]* 2 = 3`

Explanation:

To Find:

Value of expression

75 ÷ 5 - [( 9 - 7 ) × 3 ] × 2

Solution:

PEDMAS rule

It explains the order of operations to solve an expression.

According to Pedmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.),

then division, multiplication, addition and subtraction from left to right.

P - parenthesis

E- exponent

D/M - Div or Multiply which ever comes first

A/S - Add or Sub which ever comes first.

So first we will solve the Parenthesis we get

Step 1. Parenthesis operation

75 ÷ 5 - [( 2 ) × 3 ] × 2

Step 2. Parenthesis operation

`75/ 5 - [(2)* 3 ]* 2`

Step 3. Division

`15 - [6]* 2`

Step 4. Multiplication

`15 - 12`

Step 5. Subtraction

3

Therefore

`75/ 5 - [(9-7)* 3 ]* 2 = 3`
