Answer 1

A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!

Answer 2

if you mean

`\frac{1}{ {5}^( - 5) }`
then

`\frac{1}{ {5}^( - 5) } * \: \frac{ {5}^(5) }{ {5}^(5) }`

`\frac{ {5}^(5) }{ {5}^( - 5 + 5) }`

`\frac{ {5}^(5) }{ {5}^(0) }`

`\frac{ {5}^(5) }{1}`
so

`{5}^(5) = 3125`
then the answer is 4. 3125
