Answer:

\sqrt{b^{2} }=b

Step-by-step explanation:

In math the square root of the number x is the number y that when its multiplied by itself the result is x. Like this:

\sqrt{x}=y\\y*y=x

So in this case we would have to find a number that when its multiplied by itself will give us the result b^{2}. This number its b because when we multiply b by itself it gives us the result b^{2}.

\sqrt{b^{2} }=b

b*b=b^{2}

Verify if f(x)= 5-3x/2 and g(x)= 5-2x/3 are inverses. Please show step by step.
mestny [16]

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.

<h3>Inverse of functions</h3>

In order to determine if the function f(x) and g(x) are inverses of each other, the composite function f(g(x)) = g(f(x))

Given the function

f(x)= 5-3x/2 and

g(x)= 5-2x/3

f(g(x)) = f(5-2x/3)

Substitute

f(g(x)) = 5-3(5-2x)/3)/2

f(g(x)) = (5-5+2x)/2

f(g(x)) = 2x/2

f(g(x)) = x

Similarly

g(f(x)) = 5-2(5-3x/2)/3

g(f(x)) = 5-5+3x/3

g(f(x)) = 3x/3

g(f(x)) =x

Since f(g(x)) = g(f(x)) = x, hence the function f(x) and g(x) are inverses of each other.

What is .61 repeating as a fraction and how did you get the answer
vivado [14]
61/100, because if it is 0.(value) than it is value / 100 assuming value is 2 digits long. We cannot simplify it further because 61 is prime number.
