Question

Dados a= 2³ b=2¹ c= (2²)³ calcule

a) a.b.c    b) a.c____    c) (a-b)²
                      b

Answer 1

a. 8*2*64 = 1024
b. 8*64/2 = 256
c. 64-32+4 = 36

Answer 2

a )

$\boxed{2^{3}.2^{1}.(2^{2})^{3}~\to~2^3.2^{1}.2^{6}~\to~2^{3+1+6}~\to~2^{10}~\to~1024}$

b )

$\boxed{\frac{2^3.(2^{2})^{3}}{2} ~\to~ \frac{2^{3}.2^{6}}{2} ~\to~ \frac{2^{9}}{2^{1}}~\to~2^{8} ~\to~256}$

c )

$\boxed{(2^{3}-2)^2~\to~(8-2)^2~\to~6^2~\to~36}$
