若3x+2y=-2,则9的y次方乘以3的3x次方=若3x+2y=-2,则9的y次方乘以3的3x次方=若3x+2y=-2,则9的y次方乘以3的3x次方=9的y次方乘以3的3x次方=3^2y×3^3x=3

若3x+2y=-2,则9的y次方乘以3的3x次方=
若3x+2y=-2,则9的y次方乘以3的3x次方=

若3x+2y=-2,则9的y次方乘以3的3x次方=
9的y次方乘以3的3x次方
=3^2y×3^3x
=3^(2y+3x)
=3^(-2)
=1/9

9的y次方乘以3的3x次方
=(3^y)^2*3^3x
=3^2y*3^3x
=3^(3x+2y)
=3^-2
=1/9

9的y次方乘以3的3x次方=3的2y次方乘以3的3x次方=3^(2y+3x)=3^(-2)=1/9
