Respuesta :

3.30 x 10^6 times
Steps
6.57 divided by 1.99=3.302
10^36 / 10^30 =10^6
So the answer would be 3.302 x 10^6, but it has to be rounded to two significant figures to match the values in the question - so it will be 3.30 x 10^6

Answer: The black hole is [tex]3.302\times10^{6}[/tex] times more masive than the sun.

Step-by-step explanation:

Given : The mass of black hole =  [tex]6.57\times10^{36}\ kg[/tex]

The mass of Sum is approximately [tex]1.99\times10^{30}\ kg[/tex]

Now, the number of times the mass of black hole more massive than the mass of sun is given by :-

[tex]n=\dfrac{6.57\times10^{36}}{1.9\times10^{30}}[/tex]

i.e.[tex]n=\dfrac{6.57}{1.9}\times\dfrac{10^{36}}{10^{30}}[/tex]

Using the division law of exponent :-

[tex]\dfrac{a^m}{a^n}=a^{m-n}[/tex]

[tex]=\approx3.302\times10^{36-30}}\\\\=3.302\times10^{6}[/tex]

Hence, the black hole is [tex]3.302\times10^{6}[/tex] times more masive than the sun.
