Roopa and Noor try to simplify the expression 18 x 4 the power of 2 + (9-3) the power of 2. Roopa simplifies the expression and
pentagon [3]

Answer:

Noor was right because the answer is 324

Step-by-step explanation:

the BODMA rule of solving the expression the bracket first before applying the index or before multiplying.

The correct way of solving the expression is

18 x 4x 4 + (9-3)(9-3)

= 18×16 + 6×6

= 288 + 36

= 324

But

Roopa solved it this way instead

18 x 4x 4 + (9×9-3×3)

= 18×16 + (81-9)

= 288 + 72

= 360

So, Noor was right while Roopa was wrong
