Power of product-product equals power.

8.( 1) The original formula =1x1016+1x16 = 2x10/6.

② The original formula =-2a12+a12 =-a12.

(3) The original formula =-27a9+16a9-125a9 =-136a9.

9. The original formula = a (m+1+n) b (n+2+2m-1) = a (m+1+n) b (n+2m+1) = A4B.

That is (m+n+ 1)=4.

(2m+n+ 1)=5

The solution is m= 1.

n=2
