4x10^6 is how many times as large as 1x10^4?

400

Step-by-step explanation:

(4 × 10^6) / (1 × 10^4) =

= 4/1 × 10^6/10^4

= 4 × 10²

= 400

400

so the first one is 400,000

the second one is 10,000

try to subtract and if that doesn't help divide the two

Step-by-step explanation:

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

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.
