Question

Can any one help me?​

Answer 1

64

Explanation:

2x-4y=3

x= (3 +4y)/2

substitute into the main equation

y= 0

x= 3/2

16^x /256^y

16^3/2 ÷ 256^0

√16^3 ÷1

= 64

Answer 2

64

Explanation:

2x - 4y = 3

2x = 4y + 3

x = 2y + 1.5

`(16^x)/(256^y) =`

`= (16^(2y + 1.5))/(256^y)`

`= (16^(2y + 1.5))/(16^(2y))`

`= 16^(2y + 1.5 - 2y)`

`= 16^(3)/(2)`

`= 4^3`

`= 64`
