Expression: 4(4xsquared3y)1. First simplify the expression, anything squared is equal to the same expression, to the second power (^(2)).
4( 4x^(2) * 3y )
2. Further simplify by multiplying the two expressions in the barackets.
4(12x^(2)y)
3. Again remove the brackets by multiplying the external 4, by what is in the brackets.
48 (x^2)y
ANSWER: 48 (x^2)y
參考: * means multiplication
^ means to the power of.

4 * (4x² * 3y) = 16x² * 3y

16x^2 * 12y

4[4x^2(3y)]
= 4*4x^2(3y)
= 16x^2(3y)
= 48x^2y
= 4*4x^2(3y)
= 16x^2(3y)
= 48x^2y

4 à (4x² à 3y)
= 16x² à 3y
= 48 x² y
---------------
= 16x² à 3y
= 48 x² y

48(x^2)y
4*4*3 = 48
then just multiply by the variables
4*4*3 = 48
then just multiply by the variables

Since multiplication is a shorthand way of doing many additions, the correct answer is (16x^2)(12y). () added for clarity.
Suppose we substitute apple for x^2 and orange for y
4 times 4 apple 3 orange
doing it as addition:
4 apple 3 orange
+4 apple 3 orange
+4 apple 3 orange
+4 apple 3 orange
=16 apple 12 orange
