a - false

b - true

c - true

d - false

e - false

f - false

Explanation:

from the question

radius of the sun = 700,000,000

radius of Venus = 6,000,000

radius of Betelheuse = 500,0000,000,000

a) this says the radius of the sun 7 x 10^7 = 70,000,000 (having seven zeros) and this is not equal to what we were initially given in our question hence its false

b) this says the radius of the sun is 7 x 10^8 = 700,000,000 (having seven zeros) while radius of Betelheuse is 5 x 10^11 = 500,0000,000,000 (having eleven zeros) which is the same as the value we were given in the question.

c) this says the radius of Venus is 6 x 10^6 = 6,000,000 (having seven zeros) while radius of the sun is 7 x 10^8 = 700,000,000 (having eleven zeros) which is the same as the value we were given in the question.

d) this says the radius of Venus is 6 x 10^7 = 60,000,000 (having seven zeros) while radius of Betelheuse is 5 x 10^11 = 500,0000,000,000 (having eleven zeros) which is not the same as the value we were given in the question.

this applies for (e) and (f) also
