已知4x+3y-2=0,求27的y次方乘81的x次方的值已知4x+3y-2=0,求27的y次方乘81的x次方的值已知4x+3y-2=0,求27的y次方乘81的x次方的值4x+3y-2=04x+3y=2

已知4x+3y-2=0,求27的y次方乘81的x次方的值
已知4x+3y-2=0,求27的y次方乘81的x次方的值

已知4x+3y-2=0,求27的y次方乘81的x次方的值
4x+3y-2=0
4x+3y=2
27的y次方乘81的x次方
=81^x×27^y
=3^4x×3^3y
=3^(4x+3y)
=3^2
=9

∵4x+3y-2=0,
∴4x+3y=2 
(27^y)×(81^x)
=[(3^3)^y]×[(3^4)^x]
=(3^3y)×(3^4x)
=3^(4x+3y)
=3^2
=9
