\(\sqrt{2}^n=\dfrac{2^x}{8^y}\\ 2^{n/2}=2^{x-3y}\\ \dfrac{n}{2}=x-3y\\ n = 2x - 6y\)

4ln x + 7ln x - 3ln z

= 11ln x - 3ln z

= ln x^11 - ln z^3

= ln \(\dfrac{x^{11}}{z^3}\)

lol what is that.

I'd say 1.0.1.-1.2.0

Given that AB = AC, BD = BD(bc it's just the same), and angle ABD = angle CBD

First B can be used.

C can be used because hypotenuse and one side is equal

D can be used because angle ADB = angle CDB = 90 deg

A still can be used because we can use the right angles and 2 pairs of equal sides to derive that the remaining pair of sides are equal......

This is a bad question......

dilation with scale factor -1 does not make any change in size, therefore the answer is C.

First 9 digits:

3.14159265

First 9 digits after decimal point

3.141592654

SO much.

Chris: Both are correct.

But in (b) part you are supposed to use the answer from (a)...... XD

Use a table!!
