Remember that an exponent means repeated multiplication.

The exponent of 4 means you have four $\big(b^2\big)$ 's mutiplied together:

$\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)$

And then each exponent of 2 inside means you have two $b$ 's multiplied inside each set of parentheses.:

$\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)$

There are 8 b's there when you expand this out.
