If the columns are labeled a, b, c, d left to right, it appears that we have ...

  \sqrt{a}\times(b-c)=d\\\\\sqrt{49}\times(10-7)=21

The value of M is 21.

Questions like this require that you try different combinations of operations on the numbers shown to see if you can find a relationship. Here, the left column is a perfect square, so that is a clue. The difference of the numbers in the middle columns is a factor of the number in the right column -- another clue. It takes a certain amount of creative thought and familiarity with arithmetic facts. There is no "step-by-step" for a problem like this.
