Question

A=(23^51+23^50+23^52):(23^50+23^49+23^51)+49:7^2+10
B=(37^15-37^14+37^13):(37^14-37^13+37^12)-56:(2^3)+13
C=(7^47+7^46-7^45):(7^45+7^44-7^43)+156:[13^5×13^4:(13^2)^4]

Answer 1

A=(23^51+23^50+23^52):(23^50+23^49+23^51)+49:7^2+10=
=2×(23^50+23^49+23^51):(23^50+23^49+23^51)+7^2:7^2+10=
=2×1+1+10=
=2+1+10=13

B=(37^15-37^14+37^13):(37^14-37^13+37^12)-56:(2^3)+13=
=3×(37^14-37^13+37^12):(37^14-37^13+37^12)-7×2^3:(2^3)+13=
=3×1-7×1+13=
=3-7+13=9

C=(7^47+7^46-7^45):(7^45+7^44-7^43)+156:[13^5×13^4:(13^2)^4] =
=7^2×(7^45+7^44-7^43):(7^45+7^44-7^43)+13×12:(13^9:13^8) =
=7^2×1+13×12:13 =
=49+12 =61
