What is the mass of the Earth in scientific notation?

In scientific notation, Earth's mass is 5.97×1024 kg. The 5.97 part is called the coefficient; the 24 is called the exponent. Remember, an exponent simply describes how many times you are multiplying a number by itself.Step-by-step explanation:

Mathematics

Explanation : As you can see, $\sqrt{-16}$ is not a real number, and hence should be expressed as 4, being an imaginary number. Respectively $\sqrt{-64}$ will be 8. Therefore this expression boils down to $\left(3+4i\right)\left(6-8i\right)$ . All we have to do from now on is expand this expression.

Apply the rule $\left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i$ , in this case where $a=3,\:b=4,\:c=6,\:d=-8$ ,

$\left(3\cdot \:6-4\left(-8\right)\right)+\left(3\left(-8\right)+4\cdot \:6\right)i$

Let's simplify each part, $3\cdot \:6-4\left(-8\right)$ and $3\left(-8\right)+4\cdot \:6$ . Afterwards we can add , and refine.

$3\cdot \:6-4\left(-8\right) = 50$ ; $3\left(-8\right)+4\cdot \:6 = 0$

Therefore our simplified expression will be 50+0i , otherwise known as just 50. That is our solution.
