Consider a list of randomly generated 2-letter "words" printed on a paper. The letters cannot be repeated.

(a) At least how many of these "words" should be printed to be sure of having at least 8 identical "words" on the list?
(b) At least how many identical "words" are printed if there are 6501 "words" on the list?

what is

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

=240

=48
