Answer 2

To solve the expressions you provided, let's break them down step by step:

1. Expression 1: 1³ + 2² + 3¹ - 2³

   • 1³ = 1^3 = 1
   • 2² = 2^2 = 4
   • 3¹ = 3^1 = 3
   • 2³ = 2^3 = 8

   Now, let's substitute these values back into the original expression: 1 + 4 + 3 - 8 = 0

2. Expression 2: (9²:27 - 2) * 5²

   • 9² = 9^2 = 81
   • 27 is a constant.
   • 5² = 5^2 = 25

   Now, let's substitute these values back into the original expression: (81/27 - 2) * 25

   Calculate inside the parentheses first: (3 - 2) * 25 = 1 * 25 = 25

   So, the final answer is 25.

Therefore, the answers are:

1. Expression 1: 0
2. Expression 2: 25
