Which of the following is a step in simplifying the expression (xy^2/x^-3 y^3)^-4 a) x^-4 y^-2/x^-7 y^-1 b) x^-4 y^-8/x^12 y^-12 c) x^-4 y^-8/x^-3 y^3 d) x^-4 y^-2/x^-3 y^3

3=log(n)=2

answer a: product property

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

its 50 miles away from the starting point
