Answer 2

Let's break down the expression step by step:

1. ∛7 + ∛21:

   • ∛7 ≈ 1.913
   • ∛21 ≈ 2.758
   • ∛7 + ∛21 ≈ 1.913 + 2.758 ≈ 4.671

2. ∛49:

   • ∛49 = 3

3. ∛9 - √17:

   • ∛9 = 2.080
   • √17 ≈ 4.123
   • ∛9 - √17 ≈ 2.080 - 4.123 ≈ -2.043

4. √17:

   • √17 ≈ 4.123

Now let's put everything together:

(∛7 + ∛21) * ∛49 = 4.671 * 3 ≈ 14.013

∛9 - √17 * ∛9 + √17 = -2.043 * 2.080 + 4.123 ≈ -4.251 + 4.123 ≈ -0.128

So, the two expressions are not equal: (∛7 + ∛21) * ∛49 ≈ 14.013 ∛9 - √17 * ∛9 + √17 ≈ -0.128
