`93.5 xx 100` =________

100-7 times 1+5=100-(7 times1)+a . The value of a is __________.

532235 = 5 xx 100000 + 3 xx 10000 + 2 xx 1000 + 2 xx 100 + 3 xx 10 + 5

5555 = 5 xx 1000 + 5 xx 100 + 5 xx 10 + 5 xx 1

A: Total charge on N_(A) ions of CO_(3)^(2-) is 1.93 xx 10^(5) coulomb. R : Charge on one electron is 96500 coulomb.

82546 = 8 xx 1000 + 2 xx 1000 + 5 xx 100 + 4 xx 10 + 6
