a.
1.8 × 10^-6
b.
1.8 × 10^-7
c.
5.463 × 10^-6
d.
5.13 × 10^-6

Option D.

Step-by-step explanation:

The given expression is

We have to write it in the simplified form.

=

= (5.5 - 0.37)×

= 5.13×

Option D will be the answer.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
