I variant

1. 
   Amallarni bajaring
   

( 25641 : 63 – 103) * ( 265442 : 8562 + 321)
2. Masalani yeching
Kubning barcha qirralari yig`indisi 72sm ga teng bo`lsa, uning bitta qirrasi uzunligi va sirti yuzini toping.
3. Hisoblang.
( 9² - 2³ )*5¹+36
4. Harfiy ifodaning qiymatini toping.
( 19 – 7b ) + ( 9b – 8 )
5. Tenglamani yeching.
375 – (25+ y )= 135
