Answer 1

will give medal

Answer 2

3,9×10^33 ergs of radiant energy ------ 1 sec
x ---------------------------------1,55×10^7 sec
----------------------------------------------------
x = 1,55×10^7 * 3,9×10^33 = ?

hope helped

Answer 3

but how would i do this

Answer 4

you can writye it as
(1.55 * 3.9) * (10^7 * 10^33)

Multiply the 2 numbers and then use the rules of indices to combine the powers of 10

Answer 5

If you know how much it produces in 1 second, and you want to know how much it produces in some large number of seconds, logic should tell you that you need to multiply.
