I'm thinking that m2=81 is an improperly-typed equation.

m^2 = 81 is an equation that shows 81 is the product from multiplying some number m times itself.

In other words, m times m equals 81.

Have you yet learned the multiplication table?

Have you yet learned about negative numbers and their products?

Are you studying square roots?

Where are you stuck?
