The scientific notation for the product of 500 and 400 is 20 × [tex]10^4[/tex] and this can also be written as 2.0 × [tex]10^4[/tex]. So, options A and D are correct.
How to represent in Scientific notation?
- This is a way of writing very large numbers or very small numbers in the form of a number multiplied by a power of 10.
- In general form: a × [tex]10^b[/tex] where a is called as coefficient and b is called the exponent and 10 is the base.
- Where b is a positive integer for very large numbers and b is a negative integer for very small numbers.
Calculating the product:
Given numbers are 500 and 400
Their product is 500 × 400 = 200000
This is a large number.
So, the power of 10 is positive and the scientific notation is written as:
200000 = 20 × [tex]10^4[/tex]
= 2.0 × [tex]10^5[/tex]
Therefore, options A and D are correct. The product of 500 × 400 = 20 × [tex]10^4[/tex] = 2.0 × [tex]10^5[/tex].
