Answer 1

Resposta:

a) 2²+3²-1 = 12

(2.2) +(3.3) - 1

4+9-1= 12

b) 5²-3²= 16

(5.5) - (3.3)

25-9= 16

c) 27+2²-4² = 15

27+(2.2) - (4.4)

27+ 4 - 16 = 15

d) 39-5²= 14

39 - (5.5)

39-25= 14

e)10²-6²= 64

(10.10) - (6.6)

100-36 = 64

f)216-2³-3²= 199

216 - (2.2.2) - (3.3)

216-8-9= 199

g) 3³-5²+10= 12

(3.3.3) - (5.5) + 10

27-25+10= 12

h)4²+6²-7²= 3

(4.4) + (6.6) - (7.7)

16+36-49 = 3

i) 9².2²:2 = 162

(9.9) . (2.2) ÷ 2

81 x 4 ÷ 2= 162

espero ter ajudado! :)
