Write root 3 x root 6 in the form b root 2 where b is an integer

Galina-37 [17]

Answer:

$\sqrt{3}\cdot\sqrt{6}=3\cdot\sqrt{2}$

Step-by-step explanation:

<u>Radicals</u>

We have the expression:

$\sqrt{3}\cdot\sqrt{6}$

Since 6=2*3, it can be rewritten as:

$\sqrt{3}\cdot\sqrt{6}=\sqrt{3}\cdot\sqrt{2}\cdot\sqrt{3}$

Joining like radicals:

$\sqrt{3}\cdot\sqrt{6}=\sqrt{3}\cdot\sqrt{3}\cdot\sqrt{2}$

$\sqrt{3}\cdot\sqrt{6}=\sqrt{9}\cdot\sqrt{2}$

$\boxed{\sqrt{3}\cdot\sqrt{6}=3\cdot\sqrt{2}}$

This is the required form with b=2

5 - 3tan3x = 0 trên -π< x < π.

serious [3.7K]

Answer:

x = 0.343

Step-by-step explanation:

We want to solve:

5 - 3tan(3x) = 0

such that:

-π< x < π

where π = 3.14

then:

-3.14 < x < 3.14

Let's solve the equation:

5 - 3tan(3x) = 0

-3tan(3x) = -5

tan(3x) = -5/-3 = 5/3

Now we can use the inverse tan function, Atan(x).

Remember that:

Atan( tan(x) ) = tan( Atan(x)) = x

Then if we apply that function to both sides, we get:

Atan( tan(3x)) = Atan(5/3)

3x = Atan(5/3)

x = Atan(5/3)/3 = 0.343

240) What term is 359 in the sequence 5, 12, 17, 23, 28, 29......?

mamaluj [8]

Answer:

Check your question again

Step-by-step explanation:

The arithmetic equation of this sequence is an=5+(n-1)*7. Replace 359 with an and solve for n

359=5+(n-1)*7, 354/7=n-1. Wait you got the whole equation wrong, the first term should be 7 so that the common difference be equal to 5
