Answer:
All you do is just multiply them.
Step-by-step explanation:
5a^2 b^4(3ab^3)^2=
45(a^(4))(b^(10))
Answer:
Option B. 
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
substitute
Remember that
radians subtends the complete circle of area 
so
by proportion
Find the area of the related sector for a central angle of 
radians
Let
x------> the area of the related sector
Sorry dwar i am expert in biology this math is beyond my brain capacities
((-4x^3)(y^4))^-3
--------------------------
(2xy^4)^-4
16x^4y^16
=------------------------
-64x^9y^12
-16y^4
=------------------------
64x^5
-y
=------------------------
4x^5
So the final answer is:
-y^4
-------
4x^5
(Btw if "^" is in front of a number, that means it is an exponent, so when your writing this on paper, just write it as a regular exponent without the "^". I had to do that since I'm on a computer.)
Hopefully this was helpful in some way.
