How many emirp does 100 have
WebBy sig rules, any trailing zero before the decimal point does not count. For example, 1000, 100, 10 all have only 1 sig fig. E:g – 101 have 3 and 1001 have 4 significant figs respectively. How many sig figs is 60? 60 have an unlimited number of sig figs as rule depicted that all exact numbers have an unlimited number of significant figures. WebIf n has many divisors, the last digit of the base- n representation of a prime will be significantly restricted. It follows that the first digit of an emirp will also be significantly restricted. (For example, in base 10, no prime that starts with 2, 4, 5, 6, or 8 can be an emirp.)
