Answer 1

Given:

`\text{length =}8*10^4\text{ m}`
`t\text{hickness}=5*10^(-6)m`

To find the standard form of length, multiply and divide the length by 10, we get

`\text{length =}8*10^4\text{ }*(10)/(10)`

`\text{length =}(8)/(10)*10^4\text{ }*10`
`\text{Use }(8)/(10)=0.8\text{ and }10^4*10=10^(4+1)=10^5.`

`\text{length =}0.8*10^5m`

To find the standard form of thickness, multiply and divide the thickness by 10, we get

`t\text{hickness}=5*10^(-6)*(10)/(10)`

`t\text{hickness}=(5)/(10)*10^(-6)*10`
`\text{Use }(5)/(10)=0.5\text{ and }10^(-6)*10=10^(-6+1)=10^(-5).`

`t\text{hickness}=0.5*10^(-5)m`

Hence the standard form of length and thickness is

`\text{length =}0.8*10^5m`

`t\text{hickness}=0.5*10^(-5)m`
