若2x+5y=3,求4的x次方乘32的y次方的值

2x+5y=3 4^x=2^(2x),32^y=2^(5y) 所以:4^x*32^y=2^(2x)*2^(5y)=2^(2x+5y)=2^3=8 祝你开心!希望能帮到你。。。

4^X*32^Y =2^2X*2^5Y =2^(2X+5Y) =2^3 =8

你好 4^x*32^y =2^(2x)*2^(5y) =2^(2x+5y) =2^3 =8

即2x+5y=3 所以4^x*32^y =2^2x*2^5y =2^(2x+5y) =2^3 =8

2x+5y-3=0 2x+5y=3 4^x*32^y =2^(2x)*2^(5y) =2^(2x+5y) =2^3 =8

2x+5y-3=0 2x+5y=3 4的x次方X2的5y次方 =2的2x次方X2的5y次方 =2的(2x+5y)次方 =2的3次方 =8

解:由2x+5y-3=0 得2x+5y=3 则4的x次方×32的y次方 =(2的2次方)的x次方×(2的5次方)的y次方 =2的2x次方×2的5y次方 =2的(2x+5y)次方 =2的3次方 =8

2x+5y=0 4^x*32^y =2^(2x)*2^(5y) =2^(2x+5y) =2^0 =0

2x+5y=3; 4的x次方×32的y次方=2的2x次方X2的5y次方,=2的(2x+5y)次方,所以答案是8. 不知满意否?

由题意得:2x+5y=3, 4^x *32^y=2^(2x) *2^(5y)=2^(2x+5y)=2^3=8
