Question

Express the value of the following scientific notation of the normal in general number system

a). 2.7 X10 cube ​

Answer 1

`\\ \sf \longmapsto 2.7* 10^3`

`\\ \sf \longmapsto 27* 10^(-1)* 10^3`

`\\ \sf \longmapsto 27* 10^(-1+3)`

`\\ \sf \longmapsto 27* 10^2`

`\\ \sf \longmapsto 27\time 100`

`\\ \sf \longmapsto 2700`

Answer 2

2.7*10³=2700

note if power positive you add '0s' to the back eg 10³=1000 if the power is negative e.g10^-3 add to the front and a decimal e.g 0.001
