Answer:
- So you know that the height that is visible above x=0 is 74.98 m
- From x=0 below it has a total height of 518.16m to the sea floor
That tells us that we have two parts account for
- 74.98+518.16m = 593.14 m
The answer is 21
First you po perenthies which would be 8-6=2 the equation now is 5+4×(2)2
Then you to exponents which would be 2×2=4 the equation now is 5+4×4
Now you multiply 4×4=16 the equation is now 5+16
Now you add 5 and 16 to get 21
The difference is that in 4x you are multiplying 4 two times and in x4 you are multiplying 2 four times so 4x will be 4*4and x4 will be 2*2*2*2
