IF a particular galays has a total mass of 10 to the 59 grams and the average star in that galaxy has a mass of 10 to the 34 grams, approximately how many stars are there in that galaxy? Give your answer to the nearest whole power of 10 by entering the exponent only.

Respuesta :

Answer:

10²¹  stars

Also,

answer to the nearest whole power of 10 by entering the exponent only will be 21

Explanation:

Data provided in the question:

The total mass of a particular galaxy = 10⁵⁹ grams

The Average mass of the star in the particular galaxy = 10³⁴ grams

Now,

The number of stars in that particular galaxy will be

= [The total mass of a particular galaxy ] ÷ [Average mass of the star in the particular galaxy]

= 10⁵⁹ grams ÷ 10³⁴ grams

= 10⁽ ⁵⁹ ⁻ ³⁴ ⁾

= 10²¹  stars

Also,

answer to the nearest whole power of 10 by entering the exponent only will be 21
