Answer:
Step-by-step explanation:
The equation is:
√b+20 - √b = 5
The first step is we will add √b to both sides:
√b+20 -√b +√b = 5 +√b
√b+20 = 5+√b
Now take square at both sides:
(√b+20)^2 = (5+√b)^2
b+20 = 25+10√b+b
Now combine the like terms:
b+20-25-b=10√b
-5 = 10√b
Divide both the terms by 10
-5/10 = 10√b/10
-1/2=√b
Take square at both sides:
(-1/2)^2 = (√b)^2
1/4 = b
So in this type of question we add radical terms to both sides and square both sides twice....
The product of 2.7 and 1.5 is 4.05.
Answer:
all your numbers are mixed up, can you fix your question?
Answer:

Step-by-step explanation:
We have to arrange the functions given in ascending order which have eventually the least value and eventually the greatest value.
So, we get the following table representing the values of the functions for different values of x.
x : 5 10 15
: 23 38 53
: 1027 1048579 1073741827
: 31 106 231
: 15 30 45
: 1024 1048576 1073741824
: 25 100 225
As, can be seen from the table that the ascending order of the functions is given by
.
Hence, the order is
