Question

Ik a) but I need help with b)

Answer 1

`{ \rm{ {( (1)/( √(3) )) }^(7) }} \\`

• First rationalise the denominator:

`= { \rm{ {( (1 * √(3) )/( √(3) * √(3) )) }^(7) }} \\ \\ = { \rm{ {( ( √(3) )/(3)) }^(7) }}`

• Open the bracket, by distributing the power to both the numerator and denominator:

`= { \rm{ \frac{( √(3) ) {}^(6) * √(3) }{ {3}^(7) } }} \\ \\ = { \rm{ (27 √(3) )/(2187) }} \\ \\ = { \rm{ ( √(3) )/(81) }}`

b is 3 and c is 81
