Final answer:
The mass of the tree in Oakland is 500 times greater than the mass of the tree in Mapleville, which is written in standard form as 5 × 10².
Step-by-step explanation:
The question asks how many times greater the mass of a tree in Oakland is compared to the mass of a tree in Mapleville. We are given that the mass of the tree in Oakland is approximately 3 × 10⁶ kilograms and the mass of the tree in Mapleville is approximately 6 × 10⁴ kilograms.
To find out how many times greater the mass of one tree is compared to the other, divide the mass of the Oakland tree by the mass of the Mapleville tree:
3 × 10⁶ kg / 6 × 10⁴ kg = 500 times.
Therefore, the mass of the tree in Oakland is 500 times greater than the mass of the tree in Mapleville. When you write this in standard form, it's simply 5 × 10².
