Remember
![(a^b)^c=a^{bc}](https://tex.z-dn.net/?f=%28a%5Eb%29%5Ec%3Da%5E%7Bbc%7D)
note that if
![a^3](https://tex.z-dn.net/?f=a%5E3)
is a perfect cube then
![(a^3)^c](https://tex.z-dn.net/?f=%28a%5E3%29%5Ec)
is also a perfect cube when c is an integer
![(a^3)^c=a^{3c}](https://tex.z-dn.net/?f=%28a%5E3%29%5Ec%3Da%5E%7B3c%7D)
so if a number is a perfect cube then the power must be divisible by 3
8 is not divisible by 3
24 is divisible by 3
26 is not divisibley by 3
64 is not divisible by 3
the perfect cube is y^24
Answer:
84. What you did is right.
Step-by-step explanation:
A parallellogram's area is b x h. So the equation is 7 x 12=84.
Answer: 22
---------------------------------------------------------
Explanation:
The triangles are similar, so we know the corresponding sides form ratios that are equal.
Note how...
FS and ZD are the first two letters of FSB and ZDR respectively
FB and ZR are the first & last letters of FSB and ZDR respectively
Based on those two facts above, we can form this proportion
FS/ZD = FB/ZR
38/15.2 = 55/x
Solve for x
38/15.2 = 55/x
38*x = 15.2*55
38*x = 836
x = 836/38
x = 22
