We can rewrite the expression under the radical as

then taking the fourth root, we get
![\sqrt[4]{\left(\dfrac32a^2b^3c^4\right)^4}=\left|\dfrac32a^2b^3c^4\right|](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cleft%28%5Cdfrac32a%5E2b%5E3c%5E4%5Cright%29%5E4%7D%3D%5Cleft%7C%5Cdfrac32a%5E2b%5E3c%5E4%5Cright%7C)
Why the absolute value? It's for the same reason that

since both
and
return the same number
, and
captures both possibilities. From here, we have

The absolute values disappear on all but the
term because all of
,
and
are positive, while
could potentially be negative. So we end up with

Answer:
25 boxes because if you divide 590 from 23.25 it equals 25. I got 590 by subtracting 650 and 60 to make sure there is still that remaining 60 in the supply account.
Step-by-step explanation:
7)$25.50×.06=$1.53
$25.50+$1.53=$27.03
8)$66.30×.07=$4.64(actually $4.641 but have to round since it's money)
$66.30+$4.64=$70.94
9)$23.06×.065=$1.50(actually $1.4989 but have to round since it's money)
$23.06+$1.50=$24.56
10)$34.99×.0525=$1.84(actually $1.836975 but have to round since it's money)
$34.99+$$1.84=$36.83

Answer and Step-by-step explanation:
Ok, it's basically just parts of a circle circumference and area equation. Let's start first by writing down both equations.
C = 2πr
C = πd
A = π
Now, all we have to do is plug in the values into those equations!
4. C = 2π(12) A = π(
)
r = 12
d = 24 <---- (12 times 2 equals 24)
C = 24π
A = 144π <---- (12 times 12 (itself) equals 144)
5. C = π4.8 A = π(
)
r = 2.4 <------- (4.8 divided by 2 equals 2.4)
d = 4.8
C = 4.8π
A = 23.04π <------- (4.8 times 4.8 equals 23.04)
6. 20π = 2πr A = π
r = 10 <------- (20π divided by π and divided by 2)
d = 20 <------- (20π divided by π)
C = 20π
A = 100π <------- (10 times 10 equals 100)
7. C = 2πr 81π = π
r = 9 <------- (81π divided by π and square rooted equals 9)
d = 18 <------- (9 times 2 equals 18)
C = 18π <------- (2 times 9 equals 18, times π)
A = 81π
