Answer 2

Answer:

Step-by-step explanation:

Answer .3.

The reciprocal of any no. x/y is y/x

So ,-1/5 's reciprocal is 5/-1

We usually don't write negative on the denominator (quite a positive guy )

So we can say it as -5

Answer 4

(x-y )whole raise to -1

where x = -2/7 ,y= 4/7

= (-2/7-4/7) whole raise to -1

=(-6/7 ) whole raise -1 =-7/6 whole raise to 1

When the power is negative one, it will get reciprocal.

∴( x-y ) whole ...........-1 = -7/6

Where x raise to minus one minus y raise to minus 1

They will get reciprocaled

where x = -2/7 ,y= 4/7

-7/2 -. 7/4

= By LCM

-14/4 -7/4⇒-21/4

So , -7/6 ≠ -21/4

Hence proved
