Yes. I totally agree with that statement. 10/10
To solve the given equation, w need to review some rules:

The given equation is :


⇒⇒⇒⇒ rule (2)

⇒⇒⇒⇒ rule (1) and rule (2)

⇒⇒⇒⇒ rule (3)
removing the nature logarithm from both sides

∴ x = 4
So, the correct answer is option (2) ⇒⇒⇒⇒ x = 4
100+4200 is 4,300
4,300+50 is 4,350 if you rounded that to the nearest 10,000 it's 10,000
Explain cause I think you're missing something from the question
The most precise is 4.00 because that is equal to 10.16 cm and that is the most closes to an exact measurment.
