Class 9th math 3.1 solution english PCTB

Question 2: Write each of the following sets in tabular forms:

\((v) \; \) \(\left\{x \mid x=2^{n} ,n\in N\land n< 8\right\} \)

Solution:

Tabular Form:

\(\{2, 4, 8, 16, 32, 64, 128\}\)


Explanation:

\(x=2^n\) and \(n=1,2,3,4,5,6,7\), put each value of \(n\) to get \(x\).

\(x=2^1=2;\;\)\(x=2^2=4;\;\) \(x=2^3=8;\;\) \(x=2^4=16 ;\;\) \(x=2^5=32;\;\)\(x=2^6=64;\;\)\(x=2^7=128\)
