Answer:
5.2 x 10^4 is equal to 52000, and 1.3 x 10^-2 is equal to 0.013
If you multiply the two together you get 676
Explanation:
I wasn't sure if they were two separate questions or the same.
But,
5.2 times 10^4? For that you want to move the decimal point to the right (because the exponent is positive) four times.
Hence,
1. 5.2000
2. 52.000
3. 520.00
4. 5200.0
5. 52000
And so your answer ends up being 52,000.
Then, for 1.3 times 10^-2, you want to move the decimal to the LEFT (because the exponent is negative) two times. So...
1. 1.3
2. .13
3. .013
Then if you want to multiply them together, use multiplication like
52,000
x .013
156000
520000
+ 0000000
676000 (then move the decimal left three because you are multiplying by .013 to get 676000, 67600.0, 6760.00, 676.000)
And your final answer is 676.
