Question

Find the number of zeros in the expression 15×32×25×22×40×75×98×112×125​

Answer 1

we will get a zero for one (5*2)

15=5*3

32=2*2*2*2*2

25=5*5

22=2*11

40=2*2*2*5

75=3*5*5

98=2*7*7

112=2*2*2*2*7

125=5*5*5

therefore no. of pairs [5*2] are 9 .

therefore total no. of zeros are 9.

Hope this helps!
