Question

3^8*3^5/3^9И​

Answer 1

1.3^8*3^5/3^9=3^4

2.2 - 3(2x + 2) = 5 - 4x

x=-4,5

Answer 2

$\frac{ {3}^{8} \times {3}^{5} }{ {3}^{9} } = {3}^{8} \times {3}^{5} \div {3}^{9} = {3}^{8 + 5 - 9} = {3}^{4} = 81.$

2 - 3 ( 2х + 2 ) = 5 - 4х

2 - 6х - 6 = 5 - 4х

-6х + 4х = 5 - 2 + 6

-2х = 9

х = 9 ÷ (-2)

х = -4,5.

Ответ : х = -4,5.

Answer 3

To simplify the expression, you can combine the terms with the same base (which is 3 in this case) by using the rules of exponents. When you multiply terms with the same base, you add their exponents, and when you divide terms with the same base, you subtract their exponents.

Let's simplify the expression step by step:

1. 3^8 * 3^5 / 3^9

Now, apply the rules of exponents:

2. 3^(8 + 5) / 3^9

3. 3^13 / 3^9

Now, to divide terms with the same base, subtract the exponents:

4. 3^(13 - 9)

5. 3^4

So, the simplified expression is 3^4, which is equal to 81.
