Explain the difference in evaluating x^2 and x2. Let the value of x be 5. *

the difference in between x^2 and x2 or 5^2 and  5(2) is that since 5^2 is an exponent you have to multiply it by itself while 5(2) is getting us the sum of 5 by itself added twice.

Step-by-step explanation:

5 (2) = 5 + 5

5^2 = 5 * 5

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
