If (400)(7,000) = (28,000)(100^x), what is the value of x?
Choose the correct choice from the following.
A) 5  B) 4  C) 3  D) 2  E) 1
(400)(7,000) = (2,800)(100^x)   =&gt; (400)(7,000)/2,800 = 100^x   =&gt; 100 = 100^x   =&gt; 100^1 = 100^x   Since, base is same so powers will be same too.   So, x=1   Answer will be 1
<result>E</result>
