(16−8)×2+4(16−8)×2+4

16−(8×2+4)16−(8×2+4)

16−8×(2+4)

Answer 1

Hello :),
=(16−8)×(2+4)(16−8)×(2+4)
=8×6×8×6
=2 304
==========================================================
=(16−8)×2+4(16−8)×2+4
=8×2+4×8×2+4
=16+32×2+4
=16+64+4
=84
==========================================================
=16−(8×2+4)16-(8×2+4)
=16-20×16-20
=-4×(-4)=16
==========================================================
=16−8×(2+4)
=16-8×6
=16-48
=-32
==========================================================

Answer 2

None of the numerical expressions has a value of 20. Then all the options are incorrect.

What is simplification?

Simplification is to make something easier to do or understand and to make something less complicated.

The expressions are given below.

A.  (16 − 8) × (2 + 4) (16 − 8) × (2 + 4) = 2304

B.  (16 − 8) × 2 + 4 (16 − 8) × 2 + 4 = 84

C.  16 − (8 × 2 + 4) 16 − (8 × 2 + 4) = -324

D.  16 − 8 × (2 + 4) = -32
