Answer:
125
Step-by-step explanation:
We're looking for a number that we can multiply three of the same number to get. For example, 25 is a perfect square, because 5*5 = 25.
You can test these all on your calculator, if you're allowed! Just take the third root of all of them, and if it's a whole number, you know you have a perfect cube.
The answer, though, is 125, because 5*5*5 = 125.
that log4x=2log16x. (ii)Show that log x=3logb³ x. (iii) Show that log₂x=(1+log₂3)logix
Answer:

Step-by-step explanation:
Draw the second altitude MB (see attached diagram).
Quadrilateral HLMB is a rectangle, then LM = HB = 3 units.
Trapezoid KLMN is isosceles trapezoid (because KL=MN), thus

Triangle LHN is right triangle, then by Pythagorean theorem,

Consider right triangle KLH. In this triangle,

So,
