Answer:

Step-by-step explanation:

1.

5^x    = 5^8

5^(-2)

That is,  

5^x =  5^8 *  5^(-2)

5^x =  5^(8-2)

5^x  =  5^6

Therefore,

x=6

2.

3^5  

3^(-6)

=3^5 * 3^6

=3^(5+6)

=3^11

3.

Any number to the power zero is 1

Therefore answer is 1

4.

-1 1

  7

= -6

   7

Therefore multiplicative inverse is  -7

                                                           6

=(4 * -7 * -7)(p * q^3 * pq)

=196 p^2 q^4
