a student was working on this problem:
(a^n means the a to the nth power)
Solve for x the following equation: 6^2 + 7^2 = x^2
The goal is to write a true statement that says x = n when n is numerical value like 3.4. The student did not know where to begin.
I reversed the statement to say: x^2 = 6^2 + 7^2 (if a = b, then b = a)
Now the student knew what to do:
x^2 = 36 + 49
x^2 = 85
x = +/-9.2
