The prime factorization of 36 written in exponential notation is: 22 x 32
Use a factor tree. 36 18,2 9,2,2 3,3,2,2
Yes because 25x2-70x+49 = (5x-7)(5x-7) when factored
The prime factorization of 1296 is 2^4 x 3^4. That makes the square root 2^2 x 3^2 or 36, -36
25x2 + 40x + 16 = 25x2 + 20x + 20x + 16 = 5x(5x + 4) + 4(5x + 4) = (5x + 4)(5x + 4) or (5x + 4)2
