Question

160: {17+[3^3.5-(14+2^7:2^4)]}

Answer 1

\(160:\left\{17+\left[3^3\cdot5-\left(14+2^7:2^4\right)\right]\right\}\)

\(=160:\left\{17+\left[27\cdot5-\left(14+2^3\right)\right]\right\}\)

\(=160:\left\{17+\left[135-\left(14+8\right)\right]\right\}\)

\(=160:\left[17+\left(135-22\right)\right]\)

\(=160:\left(17+113\right)\)

\(=160:130\)

\(=\dfrac{16}{13}\)

Answer 2

160 : { 17 + [ 3 3 ⋅ 5 − ( 14 + 2 7 : 2 4 ) ] } = 160 : { 17 + [ 27 ⋅ 5 − ( 14 + 2 3 ) ] } = 160 : { 17 + [ 135 − ( 14 + 8 ) ] } = 160 : [ 17 + ( 135 − 22 ) ] = 160 : ( 17 + 113 ) = 160 : 130 = 16 13
