When you have multiplying with same base, you add the power, for example here : z^6 * z^3 = z^(6+3) = z^9.
When you have dividing with the same base, you substract it, for example here : z^9/z^4 = z^(9-4) = z^5.
Sum of ( 2x-5y) and (x+y)?
=2x-5y+x+y
=3x-4y
The second one is correct
20.41 is what the correct answe
Answer:
About 34 workers
Step-by-step explanation:
200/30 to find on average how many trees can be carved by one worker
The answer is 6.666, so just 6
Then 6*4=24 to figure out how many more trees can be carved by (4 more) workers
So, add 4 to 30 and about 224 trees can be carved.
