Answer 1

5⁴ x(5² x 5⁴)²:25⁸=
=5⁴ x (5⁶)²:(5²)⁸=
=5⁴x 5¹²:5¹⁶=
=5¹⁶:5¹⁶=1

10³:{118+7³:[(2 x 5²)²:50-1]}=
=10³:{118+7³:[(2 x25)²:50-1]}=
=10³:[118+7³:(50²:50-1)]=
=10³: [118+7³(:50-1)]=
=10³:(118+7³:49)=
=10³:(118+7³:7²)=
=10³:(118+1)=10³:119

Answer 2

   5^4 * (5^2*5^4)^2 : 25^8 = 
= 5^4 *( 5^6)^2 : (5^2)^8 = 
= 5^4 * 5^12 : 5^16 = 
= 5^16 : 5^16 = 
= 1 

   10^3 : {118 + 7^3 : [(2*5^2)^2 : 50 - 1]} = 
= 10^3 : {118 + 7^3 : [2^2 * 5^4 : (2 *5^2) - 1]} =
= 10^3 : {118 + 7^3 : [(2*5^2) - 1]} =
= 10^3 : [118 + 7^3 :(50-1)] = 
= 10^3 : (118 + 7^3 : 7^2) = 
= 10^3 : (118 + 7) = 
= 10^3 : 125 = 
= (2*5)^3 : 5^2 = 
= 2^3*5^3:5^2 = 
= 2^3 * 5 = 
= 8*5 = 
= 40
