5a x a = 5a2
5a^(3) if the x means multiplication. 5a^(3)x^(3) if the x is a variable.
The answer depends upon what the "x" here means. x is commonly used in algebra to denote a variable. However "x" is also a symbol used to mean multiplication. If the first then 5xa means 5 multiplied by x multiplied by a. If the second then 5xa means 5 multiplied by a. This is usually written simply as 5a.
Oh, dude, 5a x 5a is just 25a^2. It's like multiplying 5 by 5 to get 25, and then you just stick that 'a' in there twice because math said so. So yeah, 25a^2, easy peasy lemon squeezy.
5a = a + a + a + a + a
