Question

Answer 1

1: \(\dfrac{2^3}{64}=\dfrac{2^3:2^3}{64:2^3}=\dfrac{1}{8}\)

2: \(\dfrac{2^4}{128}=\dfrac{16}{128}=\dfrac{16:16}{128:16}=\dfrac{1}{8}\)

3: \(\dfrac{64}{2^9}=\dfrac{2^6}{2^9}=\dfrac{2^6:2^6}{2^9:2^6}=\dfrac{1}{2^3}=\dfrac{1}{8}\)

4: \(\dfrac{16}{2^5}=\dfrac{16}{32}=\dfrac{16:16}{32:16}=\dfrac{1}{2}\)

Answer 2

`1, (2^3)/(64) = (2^3)/(2^6) = 1/(2^3) = 1/8`

`2, (2^4)/(128) = (2^4)/(2^7) = 1/(2^3) = 1/8`

`3, 64/(2^9) = (2^6)/(2^9) = 1/(2^3) = 1/8`

`4, 16/2^5 = (2^4)/(2^5) = 1/2`

 

Answer 3

\(1,\dfrac{2^3}{64}=\dfrac{2^3}{2^6}=\dfrac{1}{2^3}=\dfrac{1}{8}\)
\(2,\dfrac{2^4}{128}=\dfrac{2^4}{2^7}=\dfrac{1}{2^3}=\dfrac{1}{8}\)
\(3,\dfrac{64}{2^9}=\dfrac{2^6}{2^9}=\dfrac{1}{2^3}=\dfrac{1}{8}\)
\(4,\dfrac{16}{2^5}=\dfrac{2^4}{2^5}=\dfrac{1}{2}\)
 

Answer 4

`(2^3)/64 = (2^3)/(2^6) = 1/(2^3) = 1/8`

`(2^4)/128 = (2^4)/(2^7) = 1/(2^3) = 1/8`

`64/(2^9) = (2^6)/(2^9) =1/(2^3) = 1/8`

`16/(2^5) = (2^4)/(2^5) = 1/2 `
