英语数学比例问题!!!速度要快~

一台影印机放大的比例是7比4.
一张图片尺寸是6cm长4cm宽.
请问可以连续放大多少次,使得放到最大后的图片能够印到一张长为30cm宽为20cm的纸上?

解答:
放大n次,使得放大后的长和宽均小于等于纸张的长和宽。
所以 6*(7/4)^n<=30 而且 4*(7/4)^n<=20
所以得到 (7/4)^n<=5
所以 n<=log5/log(7/4)
运算得约为2.876
n肯定是正整数,所以n最大只能取2
所以最多可以连续放大两次

之所以用is,是因为真正的位于动词是第二个be!前面的be going to 只用于构成时态,不是句子的谓语,不参与主谓一致变化。
