若2x+5y-3=0，求4的x次方乘32的y次方的值

---

结果是8.4=2的平方,32=2的5次方.换成同底的就好算了..结果是2的袭毁3次方.
X=(3-5Y)/2
`X```Y``(3-5Y)/2```Y``2*(3-5Y)/拍顷备2``5Y``3-5Y``5Y```3
4 *32 =4````````*32 =2``````````*2``=2````*2```=2 =8
上面一行是指数乎乱,你应该能看懂吧?

4^x×32^y = 2^2x×2^5y = 2（桥孝颂2x+5y）
因为2x+5y-3=0，敏郑所以2x+5y=3，代入上式慎瞎
原式= 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^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
