To evaluate a formula is to try and solve or simplify it. For instance f(x) = 2x*4x-1x+6 f(x) = 7x+6 f(3) = 7*3+6
81 x 9 = 729 9 x 9 x 9 = 729 3 x 3 x 9 x 9 = 729 and so on ...
2x-1x or x equals 1x or x 2x-x=x
if is (x-6)-(1x-1) = -5 if id (x-6)-(1x+1) = -7
All these will result in 729: 1 x 729, 3 x 243, 9 x 81, 27 x 27, 81 x 9, 243 x 3, 729 x 1
A= 243 x 3, 729 x 1, 81 x 9.
1
9 x 9 x 9 = 729
It can be simplified to: x-5y
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
729 27 x 27 = 729 9 x 9 x 9 =729
1, 3, 9, 27, 81, 243, 729: (1 x 729, 3 x 243, 9 x 81, 27 x 27)
