Question

Algebra help please!!! (Dividing powers)

An important source of food for whales, seals, and penguins that live in and around Antarctica is a shrimp-like crustacean called krill. Suppose a group of research scientists estimate that there are approximately 3^15 individual krill in a 3^7 cubic meter section of the Antarctic Ocean. About how many krill are there per cubic meter in this part of the ocean?

Pls show all work so I can better understand it, thx :)

Answer 1

Hi

$3^{15}\text{ krill in }3^{7}\text{ m}^3$

So  $\dfrac{3^{15}}{3^7}=3^{15-7}=3^{8}\text{ krill in 1m}^3$
