Answer:

Step-by-step explanation:
The problem needs application of law of indices

This means common power for terms can be applied to each term individually.

Separate power for the terms having same base can be added together.
_______________________________________________________
we will be using these law of indices in the problem

applied the first rule of indices as mentioned above

applied the second rule of indices as mentioned above
Thus, simplified form of (3xy)^2x^4y is
.
Answer:
D) 20
Step-by-step explanation:
x^2 + (y - 2)^2=100
This can be rewritten as
(x-0)^2 + (y - 2)^2=10^2
This is in the form
(x-h)^2 + (y - k)^2=r^2
The radius is 10
The diameter is 2 times the radius
d = 2*r = 2*10 = 20
6 and -2 multiplied by each other = -12 and added together = 4
