很简单的题，假设ce和df的 交点 为h，则 四边形 achf的 内角 和+四边形bdeg的内角和=360°+360°=∠a+∠b+∠c+∠d+∠e+∠f+∠g+∠chf+∠hde+∠hed，而根据 三角形的外角 定理. 计算器运算结果为几e+几（比如1e+1）是什么意思这个是科学计数法的表示法，数字超过了计算器的显示位数而使用了科学计数法。 e是exponent，表示以10为底的指数。aeb 或者 aeb (其. What you want is to write the same number in a more familiar notation (which dleggas's answer shows you how to do).

Without the use of calculators find which one is greater: No, the e+04 means multiply the displayed value by $10^4$. If there are digits that don't fit, the number is rounded, but.
The number is should like this on.
3.199 e +01 is the equivalent of $3.199\times10^1$. Strictly speaking, 1e+11 is a number; The $3.199$ part is the mantissa, e stands for exponential, and $+01$ is the exponent (in base 10).
