Answer 1

2^0+5•(5^100+5^99+5^98):5^98+343:7^2=
=1+5•(5^2+5+1)•5^98:5^98+343:49=
=1+5•(25+5+1)•5^98:5^98+7=
=1+5•31•5^98:5^98+7=
=1+155•1+7=
=1+155+7=
=163

Answer 2

2^0 + 5 × (5^100+5^99+5^98) : 5^98 + 343 : 7^2 =

= 1 + 5 × 5^98 × (5^2 + 5^1 + 1) : 5^98+ 343 : 49 =

= 1 + 5 × (25 + 6) + 7 =

= 1 + 5 × 31 + 7

= 1 + 155 + 7 =

= 163
