So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation 
which simplifies to
Find a : b:c. (a) a:b=5:3 and b:c=6:5

Changes in a coordinate 
can be observed with 90 degree rotations about the origin.
90 degrees CW =
180 degrees CW =
270 degrees CW =
Let's observe M(10, 12) and M'(12, -10).
Since they switched and the x value became negative, it must have been a 90 degree rotation.

to answer on cube root we need to use the prime factorisation.
which means using only prime number and dividing the number by suitable prime number.
after find prime factorisation we know that cube root is 3th power of number.
so if we have same three number we need to take it as one because it is a cube root .
for example
