There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So, There are 5 significant numbers in 7.9800

g) 98.0010

There is decimal point in this number. Digits on left side and right side of the decimal are considered significant

So, There are 6 significant numbers in 98.0010

h) 0.0087600

There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.

So, There are 5 significant numbers in 0.0087600

i) 0.00202
