Multiplication/division and addition/subtraction are in no particular order; solve from left to right.

6 × 10⁸

Exponents first. Find 10 to the 8th power. Move the decimal (imaginary decimal in front of the 0 in 10) 8 places to the right.

6 × 1,000,000,000

Now multiply 6 by 10⁸.

6,000,000,000 is the answer to 6 × 10⁸.

Now let's solve 3 × 10⁶

Exponents first; solve 10 to the 6th power. Move the decimal point at the front 6 places to the right.

3 × 10,000,000

Multiply.

30,000,000 is the answer to 3 × 10⁶.

Compare both answers: 6,000,000,000 and 30,000,000

Looking at them, you can see that 6 billion has 9 zeros and 30 million has 7 zeros.

Each zero counts for 100; 9 - 7 = 2 (or you can use a calculator to solve 6,000,000,000 ÷ 30,000,000)

You can conclude that 6 × 10⁸ is B) 200 times larger than 3 × 10⁶.

Let me know if you need any other help

Step-by-step explanation:

1. subtract 2 from both sides

6x+2-2=9x-1-2

2. Simplify

6x=9x-3

3. Subtract 9x from both sides

6x-9x=9x-3-9x

4.simplify

-3x=-3

5.divide both sides by -3

-3/-3=-3/-3
