Question

If X = $open square brackets table row 1 1 row 1 1 end table close square brackets$ , then Xⁿ, for n $element of$ N, is equal to -

2^n–1 X
n²X
Nx
2ⁿ⁺¹ X

The correct answer is: 2^n–1 X

$therefore$ Xⁿ= $open square brackets table row cell 2 to the power of n – 1 end exponent end cell cell 2 to the power of n – 1 end exponent end cell row cell 2 to the power of n – 1 end exponent end cell cell 2 to the power of n – 1 end exponent end cell end table close square brackets$ $rightwards double arrow$ Xⁿ = 2^n–1. $open square brackets table row 1 1 row 1 1 end table close square brackets$
