Write a binomial with two letters and a coefficient of - 1
-x²y
Both a 2 and a · a denote the multiplication of two a's______ (judge right or wrong)
Because A2 = a × a, both A2 and a · a mean multiplication of two a's
How to calculate the multiplication of two squares?
RT, such as √ 3x √ 12
That's the square root. The multiplication of square roots is the internal multiplication, √ 3x √ 12 = √ 36 = 6
