Respuesta:

a)

√100 + √25 : ( 22 + 50 ) - 14

= 10 + √25 : ( 22 + 50 ) - 14

= 10 + 5 : ( 22 + 50 ) - 14

= 15 : ( 22 + 50 ) - 14

= 15 : ( 72 ) - 14

= 0,2083 - 14

= -13,7917

b)

( √25 + √9 ) . 4

= ( 5 + √9 ) . 4

= ( 5 + 3 ) . 4

= ( 8 ) . 4

= 32

c)

√4 + 43 - √4 + 3. ( 27: 64 )

= 2 + 43 - √4 + 3. ( 27: 64 )

= 2 + 43 - 2 + 3. ( 27: 64 )

= 45 - 2 + 3. ( 27: 64 )

= 43 + 3. ( 27: 64 )

= 46. ( 27: 64 )

= 46. (0,421875 )

= 19,40625

d)

25: ( 22 -  16) + 4. 10

= 25: ( 22 - 16 ) + 4. 10

= 25: ( 6 ) + 4. 10

= 25: ( 6 ) + 40

= 4,17 + 40

= 44,17

i)

8 + 20: 22 + 32- √16 . 2

= 8 + 20: 22 + 32 - 4 . 2

= 8 + 0,91 + 32 - 4 . 2

= 8 + 0,91 + 32 - 8

= 8,91 + 32 - 8

= 40,91 - 8

= 32,91
