Question

EXERCI 1. Express the following numbers in scientific notation : (a) 4567.32
​

Answer 1

Answer:

4.56732 x 10^3

Step-by-step explanation:

Move the decimal point after the first non-zero digit, which is 4

Count the number of decimal places moved, which is 3 decimal places

Since the decimal point was moved from right to left, power will be 'added' to the exponent (10)

So the answer would be written like this

4.56732 x 10^3

Use these rules for further conversions.

Mathematically:

4567.32

= 4.56732 (3 decimal places)

= 4.56732 x 10^3
