(8b^2)(2b^(-8))(2b^(-6))=color(green)(32b^(-12)(8b2)(2b8)(2b6)=32b12 or color(green)(32/b^12)32b12

Explanation:

Remembering that b^pxxb^q = b^(p+q)bp×bq=bp+q

Re-arrange the factors, grouping the constants together and the powers of bb separately:
(8b^2)(2b^(-8))(2b^(-6))(8b2)(2b8)(2b6)
color(white)("XXX")=(8xx2xx2)(b^2xxb^(-8)xxb^(-6))XXX=(8×2×2)(b2×b8×b6)

color(white)("XXX")=32 b^(-12)XXX=32b12
