The answer is -6
So you need to drop the word sum on -6
Step-by-step explanation:

Answer

To prove


= 0.54


= 0.5

= 1.00
Now we find out the mid point of the 0.5 and 1.00 .

(Mid point is the point lies middle of a line segment .)
Mid point = 0.75
Thus

This shows o.54 lies between 0.5 and 1.00
This means 0.54 lies right to 0.5 and left from 1.00 .
Therefore

X^3= (125/27)
To find the answer, find the cube root of both sides
x= ∛(125/27)
∛(125/27)= (∛125)/(∛27) = 5/3
Final answer: 5/3
