Answer 1

Răspuns:

a)7

b)7

Explicație pas cu pas:

a)5^140 :25^70 +8^32 :16^24 +100^25 :10^48-2^2*5^2

5^140 :(5^2)^70 +(2^3)^32 :(2^4)^24 +(10^2)^25 :10^48 -4*25

5^140 :5^140 +2^96 :2^96 +10^50 :10^48-100

5+2+100-100

107-100

7

b)(7^11)^13 *(7^13)^7 :(7^18)^13 *7^2+1^2017 -2^1 *5^2

7^143 *7^91 :7^234 *49+1-50

7+49+1-50

7
