(5%) Problem 14: In scientific notation, a number is represented as a coefficient, c, multiplying an exponential factor with base 10 and exponentias CX 10" where Sisc<10 Ine-, -2,-1,0,1,2,...) To clarify, the exponent may be a positive integer, a negative integer, or zero. The coefficient is a decimal number with exactly one non-zero digit to the left of the decimal. An expression which is not in the correct form may be put in the correct form upon multiplication by a factor of 1 = 10"/10" for some integer value of m. This expression CX 10^-^ 10 (10") 10" moves the decimal to the right by m places with an offsetting change to the exponential factor while * (10'10") = = cx 10+ moves the decimal to the left by m places with an offsetting change to the exponential factor. Apply these principles towards expressing 721.7 x 10 in proper scientific notation 10*

25% Part (a) In order to re-express the coefficient of the number 721.7x 10' presented in the problem statement with exactly one digit to the left of the decimal, the decimal point must be moved by a positive integer number of places, m. Enter the value of m. 2 ✓ Correct! 25% Part (b) Using the correct value of m from the previous step, the number presented in the problem statement, 721.7 x 10', may be re-expressed in the proper format by which of the following procedures? Divide the coefficient by 10" while multiplying the exponential factor by 10 ✓ Correct * 25% Part (c) Upon carrying out the procedure that was chosen in Parts (a) and (b), the number from the problem statement, 721.7 X 10' is expressed in the proper format CX10" where ſisc<10 Pe... -2,-1,0,1,2, ...) Enter the value of the coefficient c.
