Question 842912
The Earth's crust is divided into large pieces called tectonic plates.
 The Pacific tectonic plate is moving northwest at a rate of about 4^-2m each year.
 At this rate, how long will it take the plate to move 4^6m (about 2.5 miles)?
:
Just follow the rules of exponents:
{{{4^6/4^-2}}} = {{{4^((6+2))}}} = {{{4^8}}}, About 65,536 years
