7m^47m4

Explanation:

7m^2xxm^2 = 7m^2m^27m2×m2=7m2m2

This is one rule for exponents, a^b*a^c=a^(b+c)abac=ab+c

So, we leave the 77 aside and we will focus on the m^2m^2m2m2

m^2m^2=m^(2+2)=m^4m2m2=m2+2=m4

7+m^4=7m^47+m4=7m4

There's your answer. 7m^47m4

If you were talking about something else like find mm, you need to specify the =... as you need an answer in order to find m.
