Mars2501 [29]

Answer:

<h2>Option B is the right answer.</h2>

Step-by-step explanation:

\sqrt{3} , \sqrt{2} are two irrational numbers, that is, they can not be shown as the fraction of two integers.

\sqrt{3} \times\sqrt{2} = \sqrt{6}

\sqrt{6} is also a irrational number, since it also can not be represented as the fraction of integers.

45 Points, Question 2 In Attachment. Asap if possible.
Masja [62]

Answer: x = \frac{-5}{2}

Step-by-step explanation:

3^{4x-5} = (\frac{1}{27}) ^{2x+10}

1/27 can be written in index form as 3^{-3}

The equation then becomes:

3^{4x-5} = (3^{-3})^{2x+10}

Equating the coefficient

4x - 5 = -3 ( 2x + 10)

4x - 5 = -6x - 30

10x = -30 + 5

10x = -25

x = -25/10

x = -5/2

x = - 2.5
