Answer:
A = (-8)
m = 7
n = 4
Step-by-step explanation:
[tex](-2x^{3} y^{2} )*(4x^{4} y^{2} )\\(-2*4)(x^{3}*x^{4})(y^{2} *y^{2} )\\-8*x^{(3+4)} *y^{2+2} \\-8x^{7} y^{4} \\[/tex]
In the question, they have given that the answer is equal to,
[tex]-8x^{7} y^{4} =Ax^{m} y^{n}[/tex]
There fore,
[tex]A = (-8)\\m=7\\n=4[/tex]
Hope this helps you.
