Question

What value of xwill make x3/2=8 true?

Answer 1

x = ∛2^4 which is approx. 2.5

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

Answer 2

is it x to the power of 3 or 3x over 2=8?
