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....

Riemann sums help us approximate definite integrals, but they also help us formally define definite integrals. Learn how this is achieved and how we can move between the representation of area as a definite integral and as a Riemann sum.
Definite integrals represent the area under the curve of a function, and Riemann sums help us approximate such areas. The question remains: is there a way to find the exact value of a definite integral?
