Question

Help me with question 4 and 5

Answer 1

Answer:

2.6768·10^(-14)  (Answer C)

Step-by-step explanation:

Problem 4:  We ADD the powers of 10:  10^6·10^(-3) = 10^3.  Also, 3.6·1.7 = 6.12.  Therefore, Answer D is correct.

Problem 5:  Again we ADD (combine) the powers of 10:  10^(-10)·10^(-5) =

10^(-15).  4.78·5.6 = 26.768.  Our intermediary answer is thus:

26.768·10^(-15).  This must be rewritten in the form x.xxxx, so here we have:

2.6768·10^(-14)  (Answer C)
