1 answer:
Tanya [424]4 years ago
7 0

I believe this problem have these following choices:

5,000 cal

0.05 cal

5 x 10^3 cal

5 x 10 ^4 cal

 

<span>Now 1 kilocalorie  = 1000 calories, therefore:</span>

 

50 kilocalories * (1000 calories / 1 kilocalorie) = 50,000 calories

 

 

Since there are 4 zeroes, so the scientific notation is:

 

5 x 10 ^4 cal         (ANSWER)
