12/10, 1.2, and any of the infinite multiples of the fraction such as 24/20, 120/100 etc...
For this case what we have to take into account are the following properties:
1) In a division, same base, the exponents are subtracted.
2) Opposite signs are subtracted.
3) Equal signs are added and the sign of the major is left.
4) Power powers multiply.
Answer:
a ^ 9b ^ 6
See attached image for the procedure.
9 walleye should be put into the pool to model the conditions in the lake .
<u>Step-by-step explanation:</u>
Here we have , A scientist estimates that there are 2.2×107 walleye in Lake Erie. The total ‘volume of Lake Erie is 4.83×1011 cubic meters. A pool with a volume of 200,000 cubic meter is built to model the lake. We need to find How many walleye should be put into the pool to model the conditions in the lake . Let's find out:
In 4.83×1011 cubic meters , there are 2.2×107 walleye . So , in 1 cubic meters :
⇒
According to question we need to find , Number of walleye should be put into the pool of volume 200,000 cubic meter :
⇒
⇒
⇒
⇒
⇒
Therefore , 9 walleye should be put into the pool to model the conditions in the lake .
