Work Step by Step

RECALL: To write $a(10^n)$ in standard form, the decimal point will be moved: (i) $n$ places to the right when $n$ is positive; or (ii) $|n|$ places to the left when $n$ is negative. The given expression has $n=-2$. Thus, move the decimal point 2 places to the left to obtain: $8(10^{-2}) = 0.08$
