3m to the power of 2 = 222

What is the value of m?

if it is 3m^2 then √74 if you meant (3m) ^2 it is √74/3

Step-by-step explanation:

if the first then you divide 3 from both sides thus getting m^2 = 74, and you get m=√74, if second then you get 9m^2 and you divide 9 from both sides and get m^2 = 2.4 (8) and you square that to get √74/3
