Express the following numbers in standard form:

(i) 5, 00, 00, 000

(ii) 70, 00, 000

(iii) 3, 18, 65, 00, 000

(iv) 3, 90, 878

(v) 3, 9087.8

(vi) 3908.78

(i) We have to express the given number in standard form:

Thus,

5, 00, 00, 000 = 5 × 10^{7}

(ii) We have to express the given number in standard form:

Thus,

70, 00, 000 = 7 × 10^{6}

(iii) We have to express the given number in standard form:

Thus,

3, 18, 65, 00, 000 = 3.1865 × 10^{9}

(iv) We have to express the given number in standard form:

Thus,

3, 90, 878 = 3.90878 × 10^{5}

(v) We have to express the given number in standard form:

Thus,

39087.8 = 3.90878 × 10^{4}

(vi) We have to express the given number into standard form:

Thus,

3908.78 = 3.90879 × 10^{3}
