Question

Which expression is equivalent to (21x^−2)^0 ?(1 point) Responses 3x^2⋅(1/7)x^−2 3 times x squared times 1 seventh x to the negative 2 power (21x^12y)^1 open paren 21 x to the 12th power y close paren to the 1th power 7x^2/7x^2 the fraction with numerator 7 x squared and denominator 7 x squared 0x^2⋅21x^4

Answer 1

?

Answer 2

no

Answer 3

7x^2/7x^2

Answer 4

Sorry about that, my previous response was incorrect.

The expression (21x^-2)^0 = 1, because any non-zero number raised to the power of 0 is always 1.

So, the correct answer is: 1.

Answer 5

I apologize for the confusion.

Let's walk through the expression step by step:

(21x^-2)^0

Any number (other than 0) raised to the power of 0 is always equal to 1. Therefore, this expression simplifies to:

1

So, the correct expression equivalent to (21x^-2)^0 is 1.
