What expression is equivalent to (a^-8 b/a^-5 b^3)

Step-by-step explanation:

There's more than 1 way this can be represented.

a: a^-8/a^-5

a: a^(-8 + 5)

a: a^-3

b: b / b^3

b: b^(1 - 3)

b: b^(-2)

So one of the answers could be

a^-3*b^-2

Another could be

1/(a^3*b^2)

There are other ways, but these are the main 2. If you have choices list them.

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.
