若3x+5y=3,求8^x×32^y的值若3x+5y=3,求8^x×32^y的值若3x+5y=3,求8^x×32^y的值8^x×32^y=2^3x*2^5y=2^(3x+5y)=2^3=88^x×32
若3x+5y=3,求8^x×32^y的值
若3x+5y=3,求8^x×32^y的值
若3x+5y=3,求8^x×32^y的值
8^x×32^y=2^3x*2^5y=2^(3x+5y)=2^3=8
8^x×32^y
=2^3^x×2^5^y
=2^(3x)×2^(5y)
=2^(3x+5y)
=2^3
=8
8^x×32^y
=(2^3)^x×(2^5)^y
=2^3x×2^5y
=2^(3x+5y)
=2^3
=8
得解
8
(2^3)^x8(2^5)^y
=2^3y*2^5y
=2^(3y+5y)
=2^3
8^x×32^y
=2^3^x×2^5^y
=2^(3x)×2^(5y)
=2^(3x+5y)
=2^3
=8
