Answer:
z=27^(1/3)=3
check:3x3x3=27
Step-by-step explanation:
Hey
Mattchance666,
Lets solve this equation together,
The question we are enquiring is : What is the value of i ^20+1?
To solve this equation: we have to use the Power Reduction Rule.
Where I^n=I{n mod 4}<span>
</span>In this case: <span>I^20 = I^{5*4+0}=I^0</span>
1 + 1 = 2
Hope this helps,

Answer: 2sqrt(10)
Step-by-step explanation:
I'll do the top left one as an example, you can do the rest.
From the geometric mean theorem, we get that 5/x = x/8.
This rearranges to x^2 = 40
x = 40 = 2sqrt(10)
