Răspuns:

Explicație pas cu pas:

7²+7³{7^36:7^34+7^28:7^26]:7^4=

7²+7³(7²+7²):7^4=7²+2·7^(3+2-4)=7²+2·7=49+14=63

Answer 2

$\it 7^2+7^3\cdot\Big[(7^4)^9:7^{34}+7\cdot7^{27}:7^{26}\Big]:49^2=\\ \\ =49+7^3\cdot(7^36:7^{34}+7^{1+27-26}):49^2=49+7^3\cdot(7^2+7^2):(7^2)^2=\\ \\ =49+7^3\cdot2\cdot7^2:7^4=49+2\cdot7^{3+2-4}=49+2\cdot7=49+14=63$
