Apply the negative exponent rule, so move the expression to the denominator to make the exponents positive.
Your answer is:

r^7 + s^12
Answer:
$15.6
Step-by-step explanation:
one bag= $1.95
8 bags = 8×1.95=15.6
so answer is $15.6.
Part 1) <span>What is the maximum volume of a square pyramid that can fit inside a cube with a side length of 18 cm?
we know that
[volume of a square pyramid]=(1/3)*b</span>²*h
where
b is the length side of the square base-----> 18 cm (is equal to the length side of cube)
h is the height---------> 18 cm (is equal to the length side of cube)
[volume of a square pyramid]=(1/3)*18²*18----> 1944 cm³
the answer Part 1) is
c. 1,944 cm³
Part 2) <span>Find the volume of the cylinder in terms of Pie. The diagrams are not drawn to scale.
</span>
volume of a cylinder=pi*r²*h
for r=2.2 m
h=12 m
volume of a cylinder=pi*2.2²*12-----> volume=58.08*pi m³
the answer Part 2) is
58.08*pi m³
Perimeter:
The perimeter of the triangle is the sum of its sides.
We have then:
P = 8 + 12 + 10
P = 30 units
Semi-perimeter:
In geometry, the semiperimeter of a polygon is half its perimeter.
s = P / 2
s = 30/2
s = 15 units.
Area:
Knowing the semiperimeter and the sides, the area is:
A = root (s * (s-a) * (s-b) * (s-c))
where,
s: semi-meter
a, b, c are sides.
A = root (15 * (15-8) * (15-12) * (15-10))
A = 39.68626967
A = 40 units ^ 2
