Find pattern and replace to another pattern string

Question

I tried to check if string contains some patterns string For example: '4+3+6**4'.

I want replace the pattern ** to pow(x,y).

so i want the string will be 4+3+pow(6,4).

i want to know if there any way by 'Regex'.

trt.

Do you also want to count the pow(6,4) so that the output is 4+3+1296, or just leave it as a string? — Wiktor Stribiżew

Just capture the number which exists before and after to ** along with the match ** and then replace the match with pwo($1,$2) .

Regex.Replace(string, @"(\d+)\*\*(\d+)", "pwo($1,$2)");
