Question

520 : { [ (16 x 5 + 2² x 5 ) ) : 5 - 5  ] + 115 } + 2017 ⁰

Answer 1

\(520:\left\{\left[\left(16\cdot5+2^2\cdot5\right):5-5\right]+115\right\}+2017^0\)

\(520:\left\{\left[\left(80-20\right):5-5\right]+115\right\}+1\)

\(520:\left\{\left[60:5-5\right]+115\right\}+1\)

\(520:\left(7+115\right)+1\)

\(520:122+1\)

\(=5,2\)

Answer 2

520 : { [ (16 x 5 + 2² x 5 ) ) : 5 - 5  ] + 115 } + 2017 ⁰

= 520 : { [ (80 + 20) : 5 - 5 ] + 115 } + 1

= 520 : { [ 100 : 5 - 5 ] + 115 } +1

= 520 : { [ 20 - 5 ] + 115 } +1

= 520 : { 15 + 115 } +1

= 520 : 130 +1

= 4 + 1

= 5
