I knew = 2.2 and 2.2= 2+2
What operations have represented 2^2?

? =

3+3+3=9 ; 3.3.3=81 and continue is . what is representation for operations ? I assume to have a operation, it is called f. I have 3f3= ; =3.3.3 ; 3.3= 3+3+3; what is representation for operations f ?

• May be it's the tetration operation? Seems to me like the person is asking for $\text{plus}(\text{plus}(3,3),3)$ being multiplication, $\text{multiplication}(\text{multiplication}(3,3),3)$ being exponentiation and then moves on to asking what $\text{exponentiation}(\text{exponentiation}(3,3),3)$ is called. – Frenzy Li Jul 8 '16 at 5:36

I am not sure that I understand your question. The expression 2^2 is the same as $2^2$ and itmeans multiplying $2$ by itself $2$ times. So $$2^2 = 2\cdot 2 = 4.$$ Now it happens that $2$ plus $2$ is also equal to $4$. It is not true in general that $n^m = n + m$. For example $3^2 = 3\cdot 3 = 9$ and $3 + 3 = 6$.

• Yes i want to ask if 3+3+3=9 ; 3.3.3=81 and continue is 3^3^3. what is representation for operations 3^3^3 ? I assume to have a operation, it is called f. I have 3f3=3^3^3 ; 3^3=3.3.3 ; 3.3= 3+3+3; what is representation for operations f ? – QChí Nguyễn Jul 8 '16 at 5:27
