Answer:
The error student make is he multiply the terms instead of addition.
Step-by-step explanation:
Given : A student found the product of 8 × 10 to the 6 power + 5 × 10 to the 9th power to be 4 × 10 to 15 power.
To find : What is the error ?
Solution :
8 × 10 to the 6 power - [tex]8\times 10^6[/tex]
5 × 10 to the 9th power - [tex]5\times 10^9[/tex]
4 × 10 to 15 power - [tex]4\times 10^{15}[/tex]
According to student, [tex]8\times 10^6+5\times 10^9=4\times 10^{15}[/tex]
We solve the expression,
[tex]=8\times 10^6+5\times 10^9[/tex]
[tex]=8\times 10^6+5000\times 10^6[/tex]
[tex]=10^6(8+5000)[/tex]
[tex]=5008\times 10^6[/tex]
The error student make is he multiply the terms instead of addition.
