Answer 1

Răspuns:

Explicație pas cu pas:

a) (-10) ^12: (-100)^5+(-49)^5:343^3+ (-10)^2 =

= 10^12:(-)10^10-(7^10:7^9)+10^2 = 10^12:(-)10^10-(7^10:7^9)+10^2 =

= -10^2-7+10^2= -7

b) [5^7·(-5)^6: (-5)^12]^10:[(-5)^2]^4-(-5)^2= [5^13:5^12]^10:5^6-5^2=

= 5^10:5^6-5^2= 5^4-5^2= 5^2(5^2-1)= 25·24= 600

c) (2^5)^4:[2^5·(-2^3)^6:(-2^2)^5]= 2^20:[2^5·2^18:2^10]=

= 2^20:2^13= 2^7

d) 9^12·(-3^8):[(-9^3)^2·81]^2:[(-5^3+2^2)^5]^0= 3^24·(-3^8):[3^12·3^4]^2:1=

= -3^16:3^16= -1
