Bonjour,
rappels:
[tex] {a}^{b} \times {a}^{c} = {a}^{b + c} \\ \\ \frac{ {a}^{b} }{ {a}^{c} } = {a}^{b - c} \\ \\ ( { {a}^{b} })^{c} = {a}^{b \times c} \\ \\ {a}^{c} \times {b}^{c} = {(a + b})^{c} [/tex]

a. 4⁶*4³= 4⁹
b. (4³)⁵= 4¹⁵
c. 4³/4⁶ = 4-³
d. 3⁴*6⁴ = 18⁴

1. q-⁴*q³ = q-¹ ET 1/q ET q³/q⁴
2. (q³)-⁴ = q-¹² ET (q-³)⁴ ET 1/x¹²
3. (q³*q-⁴)/q² = q-³ ET q³/q⁶ ET 1/q³
*= multiplication
/ = division.
