Find common factor, in this case the common factor is 10x
So the answer would be 10x(x^6 - y^10)
Given:
The given expression is

To find:
The two other equivalent expressions.
Solution:
We have,

Using distributive property, we get


So, one equivalent expression is
.
On further simplification, we get


Therefore, the second and fully simplified equivalent expression is
.
Answer:
Division can be represented with ÷ as well.
Answer:
Part a) 
Part b) 
Step-by-step explanation:
see the attached figure with letters to better understand the problem
Part a) Find the length AB
Applying the Pythagoras Theorem in the right triangle ABH

where
AB is the hypotenuse (the greater side)
AH and HB are the legs of the right triangle
we have


substitute the values



Part a) Find the length AC
Applying the Pythagoras Theorem in the right triangle ABC

where
AC is the hypotenuse (the greater side)
AB and BC are the legs of the right triangle
we have


substitute
