Question

ma ajuta cineva, dau coroana!​

Answer 1

Explicație pas cu pas:

se folosesc formulele:

$\boxed {{a}^{m} \cdot {a}^{n} = {a}^{m + n}}$

$\boxed {1 + 2 + 3 + ... +n = \frac{n(n + 1)}{2}}$

$9 \cdot {9}^{2} \cdot {9}^{3} \cdot ... \cdot {9}^{2022} = {9}^{1 + 2 + 3 + ... + 2022} \\ = {9}^{ \frac{2022 \cdot 2023}{2} } = {9}^{1011 \times 2023} = \bf {9}^{2045253}$
