Write the following numbers in the usual form:

(i)

(ii)

(iii)

(iv)

(v)

(vi)

(vii)

(viii)

In cae of positive power of 10. The usual form of the number is written after multiplying the given numbers and then counts the numbers from the right and put decimal.

Step 1: Multipy the given numbers: 4.83× 10000000 = 4830000000

Step 2: Put decimal after two places from the right: 48300000.00

Step 3: Write the number after in the usual form: 48300000

In case of negative powers, decimal sifts to left equal to the power of 10.

Step 1: Here the power of 10 is negative 6.

Step 2: Therefore decimal will sift six places to the left. i.e: 0.00000302

In cae of positive power of 10. The usual form of the number is written after multiplying the given numbers and then counts the numbers from the right and put decimal.

Step 1: Multipy the given numbers: 4.5× 10000 = 450000

Step 2: Put decimal after one place from the right: 45000.0

Step 3: Write the number after in the usual form: 45000

In case of negative powers, decimal sifts to left equal to the power of 10.

Step 1: Here the power of 10 is negative 8.

Step 2: Therefore decimal will sift eight places to the left, and we write zeros before the number to make eight places . i.e: 0.00000003

In cae of positive power of 10. The usual form of the number is written after multiplying the given numbers and then counts the numbers from the right and put decimal.

Step 1: Multipy the given numbers: 1.0001× 1000000000 = 10001000000000

Step 2: Put decimal after four places from the right: 1000100000.0000

Step 3: Write the number after in the usual form: 1000100000

Step 1: Multipy the given numbers: 5.8× 100 = 5800

Step 2: Put decimal after one place from the right: 580.0

Step 3: Write the number after in the usual form: 580

Step 1: Multipy the given numbers: 3.61492 × 1000000 = 5800

Step 2: Put decimal after five places from the right: 3614920.00000

Step 3: Write the number after in the usual form: 3614920

In case of negative powers, decimal sifts to left equal to the power of 10.

Step 1: Here the power of 10 is negative 8.

Step 2: Therefore decimal will sift seven places to the left, and we write zeros before the number to make seven places . i.e: 0.000000325
