va roggg frumoss

Answer 1

n ) 1 + { 19 -9 x (5^3)^7: (5^7)^3}^1000^3 =
=1 + { 19 -9 x (5^21: (5^21}^10^9 =
=1 + { 19 -9 x 1}^10^9 =
=1 + { 10 }^10^9 =
=1+10^90

o) 3x(2^5 + 2^4 -2^3 ) + { 25^10-(5^5)^4}:(3^100-2^100)=
=3x2^3(2^2 + 2^1 -2^0 ) + { 5^20-5^20}:(3^100-2^100)=
=3x2^3(4 + 2 -1 ) + 0:(3^100-2^100)=
=3x2^3x5 + 0=
=3x8x5=120



 q) 125^5:25^7+3x{16^3x4^2x8^5 +( 7^5x3^4)^10 : (7^2)^25: 9^20}=
=5^15:5^14+3x{2^12x2^4x2^15 +( 7^5x3^4)^10 : (7^2)^25: 3^40}=
=5+3x{2^3 +( 7^50x3^40) : (7^50: 3^40}=
=5+3x{2^3 +  1}=
=5+3x9=
=5+27=32


 2x3^2- 81^10:27^5: {5^3 -5x(4^2-11)^2+ 3^5}^5 =
= 2x3^2- 81^10:27^5: {5^3 -5x(16-11)^2+ 3^5}^5
=18-3^40:3^15:{5^3-5x(5^2)+3^5}^5=
=18-3^40:3^15:{5^3-5^3+3^5}^5=
=18-3^40:3^15:{3^5}^5=
=18-3^40:3^15:3^25=
=18-3^40:3^40=
=18
