You have troubles with domains only if you have:
- Denominators
- Roots with an even degree
- Logarithms
In this case, you have neither of these three, so you can compute your function wherever you want. The domain is all real numbers.
Answer:
x = 70.71
Step-by-step explanation:
log 2x² + 2 = 6.
log 2x² + log 100= log 10⁶.
2x² × 100 = 10⁶
2x² = 10⁶/100
2x² = 10⁴
x² = 10⁴/2
x² = 5000
x = √5000
x is approximately 70.71
x = 70.71
