Question

Bài 70: b. ( 37 + 18 ). { 3250 - 15 mũ 2 . [( 4 mũ 4 - 2 mũ 5) : 16 ] }

Answer 1

\(\left(37+18\right).\left\{3250-15^2.\left[\left(4^4-2^5\right):16\right]\right\}\)

\(=55.\left\{3250-225.\left[\left(256-32\right):16\right]\right\}\)

\(=55.\left\{3250-225.14\right\}\)

\(=55.\left\{3250-3150\right\}=55.100=5500\)

Answer 2

( 37 + 18 ) . { 3250 - 15² . [ 4⁴ - 2⁵ ) : 16 ] }

= 55 . { 3250 - 225 . ( 256 - 32 ) : 16 ] }

= 55 . { 3250 - 225 . 224 : 16  }

= 55 . { 3250 - 3150 }

= 55 . 100

= 5500.
