$(-0,5)^{-4}-625^{0,25}-(2\frac{1}{4})^{-1}+19*(-3)^{-3}=\\(-\frac{1}{2})^{-4}-\sqrt[4]{625}-(\frac{9}{4})^{-1}+19*\frac{1}{(-3)^3}=\\2^4-5-\frac{4}{9}-19*\frac{1}{27}=11-\frac{12}{27}-\frac{19}{27}=11-\frac{31}{27}=10\frac{27}{27}-1\frac{4}{27}=9\frac{23}{27}$

Помогите перевести текст
As I told you already, I ат а first-yearstudeпt ofthe techпical college.
Now, let те describe ту usual working day. Му classes begiп at nine
o'clock. So оn weekdays I have to get up at seven o'clock. Му alarm clock
usually wakes те up and mу working day begins. I turn on the radio, do
mу morning exercises, take а shower and brush ту teeth. After that I get
dressed аnd соmb ту hair. Тhеn I have breakfast. I love to listen to the latest news оn the radio while I аm eating.
I leave the house at ten minutes past eight and walk to the nearest bus
stop. I live rather far from the college and it usually takes те about а quarter of аn hour to get there bу bus. Sometimes when the weather is fine and
I have eпough time I walk to the college.
As а rule we have three or four classes а day. We have lectures in differeпt subjects. Usually 1 doп't тiss ту classes because 1 waпt to pass ту
exaтinations successfully.
At twelve o'clock we have а big iпterval for lunch. That's ту favourite
time. That is the tiтe to share the Jatest news with ту friends. I prefer not
to go to the canteeп and we often have lunch in а small cafe not too far from
the college. At оnе o'clock we have to bе back to our classes. During the
working day we also have several short intervals that Jast for ten minutes.
Froт time to time 1 have to stay at the college till late in the evening
because I go to the library to get ready for ту practical classes or to write
а report. As а rule I have по free tiтe оn weekdays. So bу the еnd of the
week I get very tired.
I соте hоmе at about 7 o'clock in the evening. Му parents are already
at hоmе. We have supper together and share the latest пews. After supper
we wash dishes, drink coffee or tea and watch TV. I prefer old comedies
and serials о г films about travelling. Sometimes I go for а walk in the park
or visit ту friends.
At about eleven at night I go to bed. I like to read something before going
to bed oг to listen to some music. Sometimes I fall asleep while I am reading.
