Answer:

x = ∛2^4 which is approx. 2.5

Step-by-step explanation:

x³/2 = 8/1

cross-multiply to get:

x³ = 16

x³ = 2^4

multiply each exponent by 2/3

x^(3·2/3) = 2^(4·2/3)

x² = 2^8/3

take square root of each side:

x = 2^(8/3 · 1/2)

x = 2^4/3

x = ∛2^4

Simplify 8 over the quantity of 2 plus 2i.

dexar [7]

$\dfrac{8}{2+2i}=\dfrac{8}{2(1+i)}=\dfrac{4}{1+i}=\dfrac{4}{1+i}\cdot\dfrac{1-i}{1-i}=\dfrac{4(1+i)}{1^2-i^2}\\\\=\dfrac{4(1+i)}{1-(-1)}=\dfrac{4(1+i)}{1+1}=\dfrac{4(1+i)}{2}=2(1+i)=2+2i\\\\Used:\\(a-b)(a+b)=a^2-b^2\\\\i=\sqrt{-1}\to i^2=-1$
