Answer 1

Resposta:

1.

a) \/49 + \/16 = 7 + 4 = 11

b) \3/8 - \4/16 = 2 - 2 = 0

c) -5\/9 + 2\/169 = (-5 * 3) + (2 * 13) = -15 + 26 = 11

d) 10 \3/2 + 4 \3/2 - \3/2 = 13 \3/2

e) \/18 + 2\/50 = 3\/2 + (2 * 5\/2) = 3\/2 + 10\/2 = 13\/2

f) \/25 + \3/27 + \4/81 = 5 + 3 + 3 = 11

g) \/64 + \3/-64 + \6/64 = 8 - 4 + 2 = 6

2.

a) 3\/5 + \/5 - 6\/5 = -2\/5

b) 5 \5/3 + 2 \5/3 - 2 \5/3 + \5/3 = 6 \5/3

c) -4 + \3/5 + 2 \3/5 - 4 = 3 \3/5 - 8

d) \/50 + \/18 - \/8 = 5\/2 + 3\/2 - 2\/2 = 6\/2

e) 2 \5/3 - 2\/3 + 3\/3 + 3 \5/3 = 5 \5/3 + \/3

f) 2\/27 - 5\/12 = (2 * 3\/3) - (5 * 2\/3) = 6\/3 - 10\/3 = -4\/3

g) 4\/63 - \/7 = (4 * 3\/7) - \/7 = 12\/7 -\/7 = 11\/7

h) \/12 + \/75 + \/108 = 2\/3 + 5\/3 + 6\/3 = 13\/3
