Question

A,2 x 32 x 12 + 4 x 6 x 41 + 8 x 27 x 3

B,(2006 x 2005^2016 - 2005^2016) : 2005^2017

Answer 1

`#3107.101107`

A,

\(2\times32\times12+4\times6\times41+8\times27\times3\\ =24\times32+24\times41+24\times27\\ =24\times\left(32+41+27\right)\\ =24\times100\\ =2400\)

B,

\(\left(2006\times2005^{2016}-2005^{2016}\right)\div2005^{2017}\\ =\left[2005^{2016}\times\left(2006-1\right)\right]\div2005^{2017}\\ =\left(2005^{2016}\times2005\right)\div2005^{2017}\\ =2005^{2017}\div2005^{2017}\\ =1\)

Answer 3

2 x 3 x 12 + 4 x 6 x 42 + 8 x 27 x 3

= 2 x 12 x 3 + 4 x 6 x 42 + 8 x 3 x 27

= 24 x 3 + 24 x 42 + 24 x 27

= 24 x ( 3 + 42 + 27 )

= 24 x 72

= 1728
