Answer 2

It looks like you want to calculate the value of the expression (Li + 3)²¹. Let's break it down step by step:

1. First, calculate (Li + 3)²:

   (Li + 3)² = (Li + 3)(Li + 3)

   To expand this, you can use the formula for squaring a binomial:

   (a + b)² = a² + 2ab + b²

   In this case, a = Li and b = 3:

   (Li + 3)² = Li² + 2(Li)(3) + 3² = Li² + 6Li + 9

2. Now, you want to raise this expression to the power of 21, so you'll multiply it by itself 20 more times:

   [(Li² + 6Li + 9)]²¹ = (Li² + 6Li + 9) * (Li² + 6Li + 9) * ... * (Li² + 6Li + 9) (20 times)

   You can use a calculator or a computer program to perform this calculation because it will involve many terms and would be very time-consuming to do by hand.

Please note that "Li" typically represents the element lithium on the periodic table, but it seems like you might be using it as a variable. If "Li" has a specific numerical value, you should substitute that value into the expression before performing the calculations.
