Alarge oak tree has 2 × 10 ^ 5 leaves during its lifespan a large forest can have about 5 × 10 ^ 3 oak trees approximately how many leaves grow on large oak trees in a forest during the lifespan of the trees

1,000,000,000 leaves or 1 x 10^9 leaves

Step-by-step explanation:

One large oak tree has 2 x 10^5 leaves, so we can make that number to 200000

There are 5 x 10^3 oak trees in a forest, we can make that number to 5000

Since we want to find out how many leaves are in the whole forest we multiply: 200000 x 5000 = 1,000,000,000

So approximately there are 1 billion leaves or 1 x 10^9 leaves

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

really your just stupid if you don't know this
