Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!

Answer:
Answer: x= 6561
Answer: x= 6561Step-by-step explanation:
Let 3^7 be y
Therefore, 3^7 + 3^7 + 3^7 = y+y+y=3y
Therefore, 3^7 + 3^7 + 3^7 = y+y+y=3yHence, 3y=x
Therefore, 3^7 + 3^7 + 3^7 = y+y+y=3yHence, 3y=x3*(3^7)=x
Therefore, 3^7 + 3^7 + 3^7 = y+y+y=3yHence, 3y=x3*(3^7)=x3^8=x
Therefore, 3^7 + 3^7 + 3^7 = y+y+y=3yHence, 3y=x3*(3^7)=x3^8=xx=6561
