Question

Help me with this plz it’s 100 points

Answer 1

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*$10^{-2}$

=$\frac{9.1}{10²}$

=0.091

By comparing above different answer with the given option we get

B.$\bold{9.1*10^{-2}}$

and

C.0.091

Answer 2

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

$\\ \bull\sf\dashrightarrow 9.1\times 10^{-2}$

Note that

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