Question

(-3x的4次方乘y的3次方)/(-2/3x的N次方乘Y的2次方)=-MX的8次方Y,求M,N的值

(-3x的4次方乘y的3次方)/(-2/3x的N次方乘Y的2次方)=-MX的8次方Y,求M,N的值

Answer 1

(-3x^4*y^3)/(-2/3x^n*Y^2)=-MX^8Y
所以-m=(-3)/(-2/3)
-m=9/2
m=-9/2
x^4/x^n=x^8
x^(4-n)=x^8
4-n=8

所以m=-9/2,n=-4

Answer 2

(-3x^4*y^3)/(-2/3x^n*y^2)
=9/2*x^(4-n)*y^=mx^8*y
则4-n=8
n=-4
9/2=m

Answer 3

M=9/2
N=-4
