as positive exponents

Answer 1

Step-by-step explanation:

1 power -2 +2 power -2 + 3 power -2 x (49/36)  power -7

(Making power Positive)

1/1 power 2 + 1/ 2 power 2 + 1/3 power 2 x 36/49 power 7  

1 + 1/4 + 1/9 x  36/49 power 7

49/36 x 49/36 power -7

a power m ×a power n = a power m+n

So the Answer is 49/36 power -6

(36/49) power 6
