Question

Select all the expressions with a value of less than onex^0(-15)^0-(15)^0-(15^0)-(0.23)^0

Answer 1

You have to determine which of the given numbers are less than 1.

In order to determine that, you consider that any quantity powered to 0 is 1. That is, you have for any value x:

`x^0=1`

You consider the previoues situation to determine the numbers that are lee than 1.

Thus, for each of the given cases you have:

x⁰ = 1. It is no less than 1

(-15)⁰ = 1. It is not less than 1

-(15)⁰ = - (1) = -1. It is less than 1

-(15⁰) = -(1) = -1. It is less than 1.

-(0.23)⁰ = -(1) = -1. It is less than 1.

In all previoues cases you have considered that any number powered to 0 is 0.
