Sun- 1.4*10^9

Step-by-step explanation:

SCIENTIFIC NOTATION- 1.4*10^9=1,400,000 km.(This is nothing but 1.4 multiplied with 10^9, which is 10 multiplied by itself 9 times. )

Simplified-

1.4*10*10*10*10*10*10*10*10*10=1.4* 1,000,000,000 =1,400,000,000

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4
