The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.

Rama09 [41]

Answer:

The mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun= $M=2.13525\times 10^{30}$ kg

Mass of Mercury, $m=3.285\times 10^{23}$ kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury= $\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}$

Mass of sun/Mass of mercury $=0.65\times 10^{30-23}$

Using the property

$a^x/a^y=a^{x-y}$

Mass of sun/Mass of mercury $=0.65\times 10^{7}$

Mass of sun/Mass of mercury $=65\times 10^5$

Mass of Sun= $65\times 10^5$ times Mass of Mercury

Hence, the mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

What is the value of this expression when x = -1 and y = 2? <br><br>4x³y²

Musya8 [376]

Substituting in you get 4(-1)^3 * (2)^2. -1 cubed is -1 and 2 squared is 4. So you get -4*4 = -16 as your answer.
