The Expression is
(x^-2y^-4x³)^-2
We can combine the x terms inside the brackets using the concept;
x ^a × x^b = x^(a+b)
Therefore,
(x^-2)(x^3) = x^(3-2) = x^!
Thus we get;
(xy^-4)^-2
Using the concept
(x^a)^b = x^(ab)
Therefore
= x ^(-2×1) y^(-2×-4)
=x^-2y^8
But using the concept; x^-a = 1/x^a
Thus, x^-2y^8 = y^8/x²
Hence the simplified equation is;
= y^8/x²
Answer:

Step-by-step explanation:
l x w= 6 x 6 = 36
14x21=294
Area of a circle = pi r squared
7x7=49
49/2=24.5
24.5 x 3.14=76.93
294-76.9=217.1
For number 7 the answer should be 20%. 10 is 50% and the other 6 is 30%.
