Which expression is equivalent to (x^6y^8)^3/x^2y^2?

Masja [62]

For this case we have the following expression:
(x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2
Rewriting and for power properties we have:
(x ^ 18y ^ 24) / x ^ 2y ^ 2
(x ^ (18-2) y ^ (24-2))
(x ^ 16y ^ 22)
Answer:
The equivalent expression is given by:
(x ^ 16y ^ 22)

What is 2 meters in centimeters??

fenix001 [56]

2 meters in centimeters would equal up to 200 centimeters. Meters and Centimeters are about 1 in the same. Centi meaning 100 is just a smaller measurement.

The Perimeter of the quadrilateral is 30 centimeters. Find the length of each side. The sides are: x+5, x+3, 2x-2, x^2-2x

Nitella [24]

Answer:

9 cm, 7 cm, 6 cm and 8 cm

Step-by-step explanation:

The perimeter is the sum of all the sides.

4 sides' expressions are given, so we add them and equate to 30.

$x+5+x+3+2x-2+x^2-2x=30\\x^2+2x+6=30\\x^2+2x+6-30=0\\x^2+2x-24=0\\(x+6)(x-4)=0\\x=-6,4$

Note: we disregard the value of x = -6, because it is going to give us side with negative length, that can't happen!

So, we take x = 4

Hence, length of each side is:

x + 5 = 4 + 5 = 9 cm

x + 3 = 4 + 3 = 7 cm

2x -2 = 2(4) - 2 = 8 - 2 = 6 cm

x^2 - 2x = (4)^2 - 2(4) = 16 - 8 = 8 cm

These are the lengths of 4 sides: 9 cm, 7 cm, 6 cm and 8 cm.
