We will begin by working through Part (a): Simplify √18

To simplify a square root such as the one above, we must factor out perfect square numbers (this means we must find a number that multiplies to 18 and gives a whole number when we square root it). Using our knowledge that √9 is a perfect square, we should factor out a 9 from 18, as modeled below:

√18 = √(9*2)

We can separate this square root into two square roots multiplied together, as shown below:

√(9*2) = √9 * √2

Now, we should simplify √9, which equals 3, because 3 * 3 = 9.

√9 * √2 = 3 * √2 = 3√2

Therefore, √18 = 3√2.


Now, we can move on to the next problem: √6 * √15.

To begin this problem, we can multiply the square roots together, which means multiplying the numbers under the radical.

√6 * √15 = √(6*15) = √90

To simplify this, we use the same process as above:

√90 = √(10 * 9) = √9 * √10 = 3√10

Note: We know that this fully simplified because we cannot factor out another perfect square number from the number under the radical (10).

Therefore, your two answers are 3√2 and 3√10.

Hope this helps!

System of conics help
ZanzabumX [31]

Answer:

Solutions are (6,3) and (-2,3).

Step-by-step explanation:

From the first equation given we can write:

(x-2)^{2} = 16-(y-3)^{2}\\  

substituting for (x-2)^{2} in the second equation given we get

\frac{16-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} = 1

\frac{-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} =0

∴ y=3

Putting y=3 in the first equation we get

(x-2)^{2} = 16

x-2 = ±4

Hence x=6 or x=-2.
