Sophia's steps to evaluate the expression on
- 9 ÷ 9 when n = 3 are shown below.
gn
- 9 ÷ 9 when n = 3
9 × 3 = 27
27
- 9 = 18
18 ÷ 9 = 2
What should Sophia have done differently to evaluate the
expression correctly?
A
subtracted 9 from (27 ÷ 9)
B
subtracted (9 ÷ 9) from 27
C
divided
(27
9) by
(27 - 9)
) D
divided (27 - 9) by (27 × 9)

it 2

step-by-step explanation:

8^1/3=2

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.

probably the last option
