Meow? Math question. Which is the correct way of doing this?
Say i have a math problem of AB2 <ab squared> converting it to c.
1 Do you multiply a times b then square
2 Do you square b then multiply by a
example a = 3 b =7
if you do it by number 1 you have 3*7 = 21 then square = 441
if you do it by number 2 you have 7 squared = 49 then times 3 = 147
which is the correct answer? Meow?
i have one book that says one way and another that says the other way?
