若3x+5y=3,求8^x×32^y的值

网友回答

8^x×32^y=2^3x*2^5y=2^(3x+5y)=2^3=8
======以下答案可供参考======
供参考答案1:
8^x×32^y
=2^3^x×2^5^y
=2^(3x)×2^(5y)
=2^(3x+5y)
=2^3=8供参考答案2:
8^x×32^y
=(2^3)^x×(2^5)^y
=2^3x×2^5y
=2^(3x+5y)
=2^3=8得解供参考答案3:
8(2^3)^x8(2^5)^y
=2^3y*2^5y
=2^(3y+5y)
=2^3供参考答案4:
8^x×32^y
=2^3^x×2^5^y
=2^(3x)×2^(5y)
=2^(3x+5y)
=2^3 =8
