2051 . If m and n are whole numbers such that $m^{n}$ =121, what is the value of ${(m - 1)}^{n - 1}$ ?

A. 1000
B. 676
C. 121
D. 10
E. none of these

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

et's first find the values of m and n from the given information:

m^n = 121

121 is equal to 11^2, so we can rewrite it as:

m^n = 11^2

Now, since m and n are whole numbers, m should be 11, and n should be 2:

m = 11 n = 2

Now, we can calculate (m - n)^(n-1):

(m - n)^(n-1) = (11 - 2)^(2-1) = 9^1 = 9

So, the value of (m - n)^(n-1) is 9, not 1000. Therefore, the correct answer is not 1000; it's 9.
