What is the sum of 3 x 10 6 and 3 x 10 6?

(I don't really know what you mean by "10 6" so I'll guess it's an exponent.)

6,000,000 (six-million)

Step-by-step explanation:

First, you need to figure out the equation.

(3 x 10 to the power of 6) + (3 x 10 to the power of 6) = x

We need to figure out x, which leads to the next step.

Let's figure out what 10 to the power of 6 is. The equation would be:

10 x 10 x 10 x 10 x 10 x 10

or,

100 x 100 x 100, to make it simplified.

Either way, 10 to the power of 6 is 1,000,000 (one-million.)

Now we can simplify our equation.

(3 x 1,000,000) + (3 x 1,000,000)

Now, the basics: use PEMDAS.

First is parentheses and inside our parentheses is 3 x 1,000,000

3 x 1,000,000 is 3,000,000.

Now, our equation is final.

3,000,000 + 3,000,000 = 6,000,000.

Since we don't have any other exponents, multiplication, or division parts to the equation, we would skip to adding.

Hope this helped!
