Answer 2

Given,

x = -0.5

To Find,

The smallest value among 2x, 1/8, 1/8², 2

Solution,

Value of x = -0.5 or -1/2

Value of  2x = 2*(-1/2) = -1

Value of 1/8² = 1 / 64

Increasing order of the values = - 1, 1/8²,1/8,2

Increasing order of the values = 2x<1/8²<1/8<2

Hence, the smallest value is 2x. Option(a) is the correct answer.
