1-5^4×(5^3)^2÷5^7+3×3^3-7^5÷7^3

=1−625(53)2÷57+3(33)−75÷7^3

=1−625(1252)÷57+3(33)−75÷7¢3

=1−(625)(15625)÷57+3(33)−75÷7^3

=1−9765625÷57+3(33)−75÷7^3

=1−9765625÷78125+3(33)−75÷7^3

=1−125+3(33)−75÷7^3

=−124+3(33)−75÷7^3

=−124+(3)(27)−75÷7^3

=−124+81−75÷7^3

=−43−75÷7^3

=−43−16807÷7^3

=−43−16807/343

=−43−49
