Answer:
In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.
 To find the scale factor,we need to follow some rules:
 locate two corresponding sides, one on each figure. 
Write the ratio of one length to the other to find the scale factor from one figure to the other

Answer:
It is proved that   .
 .
Step-by-step explanation:
We already have the identity of x as  .......... (1)  .
 .......... (1)  .
So, from equation (1) we can write that 

⇒ 
⇒ 
⇒  
 
Hence, it is proved that   . (Answer)

First integrate the entire thing by letting multiplying by 1/2 the entire expression raised to exponent 1/2 - 1. That is,
                          0.5(1 + x³)^-0.5
Then, multiplying this by the derivative of those inside the parentheses. The final answer would be,
                          (0.5)((1 + x³)^-0.5)(3x²)
