Bonjour je ne comprend pas comment réduire les expressions :/ Quelqu’un peut m’aider ? Merci

Bonjour,

[tex]a = x \times y = xy[/tex]

[tex]b = 2x \times x = 2 {x}^{2} [/tex]

[tex]c = 3x \times 2 = 6x[/tex]

[tex]d = b = 2x \times x = 2 {x}^{2} [/tex]

[tex]e = {x}^{2} \times x = {x}^{3} [/tex]

[tex]f = 1 \times 2x = 2x[/tex]

[tex]g = 0 \times x = 0[/tex]

[tex]h = 5x \times 6x = 30 {x}^{2} [/tex]

[tex]i = 4 \times x \times 5 = 20x[/tex]

[tex]j = x \times x = {x}^{2} [/tex]

[tex]k = i = 4 \times x \times 5 = 20x[/tex]

[tex]l = x \times x \times x = {x}^{2} \times x = {x}^{3} [/tex]
