El resultado de \(2^{40}+2^{39}+2^{36}\) es divisible por i) 8 ii) 10 iii) 100

Explanation:

We can factor out 8 like so

2^40 + 2^39 + 2^36 = 2^3*2^37 + 2^3*2^36 + 2^3*2^33

2^40 + 2^39 + 2^36 = 2^3*(2^37 + 2^36 + 2^33)

2^40 + 2^39 + 2^36 = 8*(2^37 + 2^36 + 2^33)

Showing that 8 is a factor of 2^40 + 2^39 + 2^36

In other words, 2^40 + 2^39 + 2^36 is divisible by 8

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
