Bonjour merci de m’a Je ne comprends rien au deux exercices

Hello !

Exo 32

a) a + b = 3^3 + 3^2 = 27 + 9 = 36

a - b = 27 - 9 = 18

b) a + b = 1^17 + 2^5 = 1 + 32 = 33

a - b = 1 - 32 = -31

Exo 33

a) 2^3 × 2^2 = 2^(3+2) = 2^5

b) 5^0 × 5^7 = 1 × 5^7 = 5^7

c) (-3)^4 × (-3)^3 = (-3)^(4+3) = (-3)^7

d) (-2/3)^3 × (-2/3)^1 = (-2/3)^4

Bonne journée !

a) a+b

[tex] {3}^{3} + {3}^{2} = 27 + 9 = 36[/tex]

a-b

[tex] {3}^{3} - {3}^{2} = 27 - 9 = 18[/tex]

b) a+b

[tex] {1}^{17} + {2}^{5} = 1 + 32 = 33[/tex]

a-b

[tex] {1}^{17} - {2}^{5} = 1 - 32 = - 31[/tex]

33

[tex] {2}^{3} \times {2}^{2} = {2}^{3 + 2} = {2}^{5} = 32[/tex]

[tex] {5}^{0} \times {5}^{7} = 1 \times {5}^{7} = {5}^{7} [/tex]

[tex] {( - 3)}^{4} \times {( - 3)}^{3} = {( - 3)}^{4 + 3} = {( - 3)}^{7} [/tex]

[tex] {( \frac{ - 2}{3} )}^{3} \times {( - \frac{2}{3}) }^{1} = {( \frac{ - 2}{3}) }^{3 + 1} = {( \frac{ - 2}{3} )}^{4} [/tex]
