Answer:
log Subscript 2 Baseline 9 + 3 log Subscript 2 Baseline x.
Log₂ 9 + 3Log₂ x
Step-by-step explanation:
Log subscript 2 baseline 9 x cubed can be written as:
Log₂ 9x³
Now, let us simply Log₂ 9x³.
This is illustrated below:
Log₂ 9x³
Recall: LogMN = Log M + Log N
Log₂ 9x³ = Log₂ 9 + Log₂ x³
Recall: Log Mⁿ = nLog M
Log₂ 9x³ = Log₂ 9 + 3Log₂ x
Therefore, the answer is log Subscript 2 Baseline 9 + 3 log Subscript 2 Baseline x.

so if r is a right angle and its wants us to prove that ab =1/2pq the answer would be
Step-by-step explanation:
The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ
<h3>Balanced equation</h3>
CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy.
<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy
Therefore,
3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy
Thus, 3115 KJ of heat energy were released from the reaction
