Question

The sun produces 3.9 • 10^33 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 2.45 • 10^5 seconds?
Is my work and answer below correct..
(3.9 • 10^33) • (2.45 • 10^5)
First multiplying coefficients: 3.9 • 2.45 = 9.555
Next multiply powers of 10: 10^33 • 10^5 = 10^33+5 = 10^38
Answer is the product of the coefficients multiplied by the product of the powers of 10: 9.555•10^38
is this right

Answer 1

so then your calcule are right so the way is correct sure

Answer 2

thank you for checking my work and letting me know I did it right.
