squared 3
812 = 81 x 81 = 6,561
2b=6squared, and 6x6=36
The answer is x = 5. There is nothing to evaluate there!
The answer is 29. Bcause 2 squared is 4 & 5 squared is 25. 25+4=29.

812 = 81 x 81 = 6,561
find out what 6 squared equals. which is 6 x 6 and that equals 36
3 squared = 9 9 - 2 x 1 = 9 - 2 = 7
2b=6squared, and 6x6=36
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)
The answer is x = 5. There is nothing to evaluate there!
