Question

(4^-1/7^-1)^-1/(3^-1/7^-1)^-1 Simplify and write the answer with positive exponent​

Answer 1

Answer:

Explanation:

We change the sign of an exponent when we move the term with that exponent to the other side of the fraction.

Some examples in math:

a

–

b

=

1

a

b

and

x

y

–

z

=

x

y

z

For this question, we can change the sign of the

x

–

4

and

y

–

1

terms if we move them to the top of the fraction like this:

1

7

x

–

4

y

–

1

=

1

x

4

y

1

7

Then, since multiplying something by 1 doesn't change its value, and raising something to the power of 1 also doesn't change its value, we can remove the 1's from this fraction:

=

x

4

y

7
