1】(6+4)÷(1-0.5)=20米2】(20+5)÷(1-0.5)=50米答……

解:牡丹花:720*(5/24)=150(m²)720-150=570(m²)7+8=15玫瑰花:570*(7/15)=266(m²)海棠花:570*(8/15)=304(m²)答:略

I1) expression2) denote3) sound4) pronunciation5) perfect6) grammar7) textbook11.. 2) F. Then how do you usually learn Japanese?3) C. Do you often speak Japanese in .

(1)原式=√[n²(n+1)²+(n+1)²+n²]/n(n+1) =√{n²[(n+1)²+1]+(n+1)²}/n(n+1) =√n²[n²+2(n+1)]+(n+1)²/n(n+1) =√(n²)²+2n²(n+1)+(n+1)²/n(n+1) =√(n²+n+1)²/n(n+1) =(n²+n+1)/n(n+1) =[(n+1)²-n]/n(n+1) =1+1/n-1/(n+1)(2)原式=1+1-1/2+1+1/2-1/3+……+1+1/n-1/(n+1) 当n=2014时原式=2015 -1/2015

由n=m/M得(n为物质的量,m为质量,M为相对分子质量.)则n镁:n铜:n铁=10/24:10/64:10/56,化简即可! 这个式子化简后就等于56:21:24了啊!
