If m and n are whole numbers such that mn = 121, then the value of (m

If m and n are whole numbers such that mⁿ = 121, then the value of (m - 1)^{n + 1} is = ?

A 1000

B 676

C 121

D 10

E None of these

Correct Answer: Option A

দেওয়া আছে, mⁿ = 121

⇒ mⁿ = 11²

এখানে, m = 11 এবং n = 2

∴ (m - 1) ^{n + 1}

= (11 - 1) ^{2 + 1}

= 10³

= 1000
