a: \(6^{x}:3^3:4=2\)
=>\(6^{x}=2\cdot4\cdot3^3=2^3\cdot3^3=6^3\)
=>x=3
b: \(3\left(x-5\right)^3=81\)
=>\(\left(x-5\right)^3=\frac{81}{3}=27=3^3\)
=>x-5=3
=>x=3+5=8
c: \(7x-2x=6^{17}:6^{15}+3^8:2^6\)
=>\(5x=6^2+\frac{3^8}{2^6}=36+\frac{6561}{64}=\frac{8865}{64}\)
=>\(x=\frac{8865}{64}:5=\frac{1773}{64}\)

Everyone dreams are beautiful, no matter how small or large, whether in money or
money bags. Architecture and House Beautiful has contributed in no small merit to house
more beautiful Vietnam added.
For me, long time track House Beautiful Publications, learn, watch, taste changes
constantly ... now I know I prefer the modern style, straight road in definition, the door
wide high , colored lights. All in all overall non
-
standard and very simple, comf
ortable,
but strange, beautiful and durable. Selected interior decoration design style of modern
Asia, little furniture, just to meet daily needs, but each item must be charming and
unique.
I was very interested in the position of the stairs, it serves as
a flexible life should
be safe, bright, wide enough to walk, carry easy, rested legs, stairs should not flaunt
picky.
There are two seats previously less concerned Vietnam, now has other kitchen and
bathroom. I love the spacious kitchen, decorating fun e
nough for family gatherings over
meals daily. Kitchen is a cozy place in your home. Where close family, expressing
emotions with a favorite food, and children have the opportunity to learn to eat, learn to
speak, learning packages, learn to open ...
Also
the bathroom is now not only to bathe that part much more. Shower as the old
style: fast, compact, less expensive; bath tub is relaxing, takes time (and more money) but
the shower feeling well. Each bathroom each different creative, bath seats in the house
now in Vietnam did not lose any of the beautiful 5 star hotel.
Home is much more room as bedrooms, living room, reserve, miscellaneous office
storage ... The skill of the architect is to arrange appropriate space for all.
Tables do not know how much det
ail is enough, each person has their own tastes,
everyone is right, depending on personality. However, it is important to have enough
money problems, things are more talented architect, reputable contractors for
coordination of the three parties agreed to
a new building is nice. That's labor force
works, the mind of many workers. So, do not save that for sloppy construction and poor
quality, the consequences will be repaired later.
