standard form the question says the
usual form for 2.03 into 10 to the power
minus 5 we have four options out of
these four options we have to
mark the correct one so first option
will cannot be the answer
because it is smaller value but not that
smaller
this cannot be the answer this is a very
large value now if you check
option d it is exactly
the given form of the standard equation
standard form so i hope you have
understood how we will convert this
standard form in this form
you can check here we have 10 to the
power minus 5 and count the digits
1 2 three four four zeros and fifth
digits so
this is the concept the relation between
this and the negative exponent
how we are expressing negative with
negative numbers
or very smaller numbers with the help of
standard form these are negative
exponents
so for this question answer is option d
that is zero point zero zero zero
zero two zero three so i hope you have
