Question

Help me with this plz it’s 100 points

Answer 1

`\\ \bull\sf\dashrightarrow 9.1E{-2}`

`\\ \bull\sf\dashrightarrow 9.1* 10^(-2)`

Note that

`\\ \bull\sf\dashrightarrow 1E^n=1000...ntimes`

Answer 2

So required expression equivalent to the answer he got are:

B.
`\bold{9.1*10^(-2)}`

and

C.0.091

Answer:

Solution given:

9.1E-2

=9.1*
`10^(-2)`

=
`(9.1)/(10²)`

=0.091

By comparing above different answer with the given option we get

B.
`\bold{9.1*10^(-2)}`

and

C.0.091
