What do you think is wrong about the two numbers you circled?

Answer 1

Its option e

Why?

`\\ \sf\longmapsto 0.000354* 10^4`

It can be written as

`\\ \sf\longmapsto (354)/(10000)* 10^4`

`\\ \sf\longmapsto (354)/(10^4)* 10^4`

• Cancel 10^4

`\\ \sf\longmapsto 354`

Hence its wrongly written

d is also wrong

`\\ \sf\longmapsto 75.3* 10^2`

`\\ \sf\longmapsto (753)/(10)* 100`

`\\ \sf\longmapsto 7530`

• Its need not be simplified .
