Answer 1

Răspuns:

Alin

(1/3)⁻¹+(1/2)⁻³=3+8=11

Cornel

0+1+(-1)+9=0+1-1+9=9

Diana

2×9-(√6)²=18-6=12

Maria

2⁴-27:(3²)¹=16-27:9=16-3=13

Maria , Diana , Alin , Cornel

raspuns B

Answer 2

Răspuns:

b) Maria > Diana > Alin > Cornel

Explicație pas cu pas:

Alin: 11 ani

${\Big( \frac{1}{3} \Big)}^{ - 1} + {\Big( \frac{1}{2} \Big)}^{ - 3} = {\Big(3\Big)}^{1} + {\Big(2\Big)}^{3} = 3 + 8 = \bf 11$

Cornel: 9 ani

${0}^{2021} + {1}^{2021} + {( - 1)}^{2021} + {( - 3)}^{2} = 0 + 1 + ( - 1) + {3}^{2} = 1 - 1 + 9 = \bf 9$

Diana: 12 ani

$2 \cdot {3}^{2} - {( \sqrt{6} )}^{2} = 2 \cdot 9 - 6 = 18 - 6 = \bf 12$

Maria: 13 ani

${2}^{ {2}^{2} } - {3}^{3} : {\Big( {3}^{2} \Big)}^{ {2}^{0} } = {2}^{4} - 27 : {9}^{1} = 16 - 27 : 9 = 16 - 3 = \bf 13$

vârstele sunt: 13 > 12 > 11 > 9

Maria > Diana > Alin > Cornel
