Answer 1

Răspuns:

a)2^2+3^2=4+9=13

b)3^2•2+1=9•2+1=18+1=19

c)1+2•3^4=1+2•81=1+162=163

Answer 2

Răspuns:

a)

$2 {}^{2} + 3 { }^{2} = 4 + 9 = 13$

e)

$3 {}^{2} \times 2 + 1 = 9 \times 2 + 1 = 18 + 1 = 19$

i)

$1 + 2 \times 3 {}^{4} = 1 + 2 \times 81 = 1 + 162 = 163$

b)

$2 + 2 {}^{2} = 2 + 4 = 6$

f)

$10 - 2 {}^{3} = 10 - 8 = 2$

j)

$(2 + 3) {}^{2} = 5 {}^{2} = 25$

c)

$2 \times 3 {}^{2} = 2 \times 9 = 18$

g)

$2 - 40 {}^{3} \div 40 {}^{30} = 2 - 40 {}^{0} = 2 - 1 = 1$

k)

$(2 \times 3 + 5) {}^{2} = (6 + 5) {}^{2} = 11 {}^{2} = 121$

d)

$1 + 2 + 2 {}^{2} = 1 + 2 + 4 = 7$

h)

$3 \times (3 {}^{2} + 3 {}^{3} ) =3 \times (9 + 27) = 3 \times 36 = 108$

l)

$9 {}^{2} \times 2003 - 81 {}^{2} = 81 \times 2003 - 9 {}^{4} = 162243 - 9 {}^{4} = 155682$
