A is X^3 Y^2.
because 3 x's and 2 y's are being multiplied.
For this explanation, I will be utilizing the hidden exponent of 1.
You can put a hidden exponent of 1 to each variable without an exponent, and the value will remain the same.
Merely add the exponents of the values with the same base number, or coefficient. —> like terms
X^1 times X^1 times X^1 is X^3, and Y^1 times Y^1 is Y^2.
Our final answer is X^3 Y^2.
B is 6X^2 Y^3.
Like the first expression, we can add a hidden exponent to each VARIABLE, not number.
2 times 3 is 6, and X^1 times X^1 is X^2, and Y^1 times Y^1 times Y^1 is Y^3.
Our final answer is 6X^2 Y^3.
