Answer:

2×2×2×2×2×2×2×2×2×3×3×3

=2×2×2×3

=4×6

=24

Step-by-step explanation:

2÷13824=6912

2÷6912=3456

2÷3456=1728

2÷1728=864

2÷864=432

2÷432=216

2÷216=108

2÷108=54

2÷54=27

3÷27=9

3÷9=3

3÷3=1

Now write them as multiple =

=2×2×2×2×2×2×2×2×2×3×3×3

Group them into the pair of 3 numbers

=(2×2×2)×(2×2×2)×(2×2×2)×(3×3×3)

Take one number amongst each

=2×2×2×3

Multiply them

=4×6

=24

And here's your answer
