8¹¹

Step-by-step explanation:

Given:

8⁹ × 8²

Evaluate;

Computation:

We know that,

Mᵃ × Mᵇ = Mᵃ₊ᵇ

So,

8⁹ × 8² = 8⁹⁺²

8⁹ × 8² = 8¹¹

So,

8¹¹

- 10 + 11i

Step-by-step explanation:

note that i² = ( $\sqrt{-1}$ )² = - 1

given

3i² + $\sqrt{-121}$ - $\sqrt{49}$

= 3(- 1) + $\sqrt{121(-1)}$ - $\sqrt{49}$

= - 3 + 11i - 7

= - 10 + 11i ← in the form a + bi
