Question 1 pts
Complete the two problems below:
1. Convert 0.00346 to exponential form and explain your answer.
2. Convert 2.76 x 104 to ordinary form and explain your answer.
Your Answer:
1) 3.46 x 10-3
0.00346 is small that 1, meaning the exponent will be negative. Move the
decimal 3 places to the left to get a number between 1 and 10, making the
exponential form 3.46 x 10-3
2) 27600.
, 2.76 is greater than 1, which is shown with the positive exponent. So, we
know the ordinary form number is going to be greater than 1. I moved the
decimal 4 places to the right and got the answer of 27600 in ordinary form
for the exponential form of 2.76 x 104
1. 0.00346 = smaller than 1 = negative exponent, move decimal
3 places = 3.46 x 10-3
2. 2.76 x 104 = positive exponent = larger than 1, move decimal 4
places = 27600
