表示它后面的数是前面数的后面数次方.
1/3*3.14*5*5x=(100+25)*3.14,即1/3*25x=125,故x=5*3=15
（1）21*3.14+62*3.14+17*3.14=3.14（21+62+17）=3.14*100=314（2）758^2=（760-2）^2=760^2-4*760+4=577600-3040+4

化简后就是20/0.5=40
（3.14×8的平方×20×1/3）÷（3.14×6的平方×20）=（3.14÷314）×（8的平方÷6的平方）×（20÷20）×1/3=1×4的平方÷3的平方×1×1/3=16/27≈0.59

(3.14*7.42+2.58*3.14)/(3.25+3.14-3又1/4)=[3.14*(7.42+2.58)]/(3.25-3.25+3.14)3又1/4就是3.25=3.14*10/3.14=

正数6.595.21420整数-3091420全是有理数
y=4^x在R上是增函数∵3.14>-3.14∴4^3.14>4^-3.14
