\bf a^{\frac{{ n}}{{ m}}} \implies  \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-------------------------------\\\\
\sqrt{x}\cdot \sqrt[5]{x}\implies \sqrt[2]{x^1}\cdot \sqrt[5]{x^1}\implies x^{\frac{1}{2}}\cdot x^{\frac{1}{5}}\impliedby 
\begin{array}{llll}
\textit{same base, thus}\\
\textit{add the exponents}
\end{array}
\\\\\\
x^{\frac{1}{2}+\frac{1}{5}}\implies x^{\frac{5+2}{10}}\implies x^{\frac{7}{10}}

How do you solve st+3t=6
bonufazy [111]
You will factor out the common factor of t if you are solving for t. you will then divide both sides by (s+3) to make t the subject of the formula. for this question you can only get t in terms of s.
so:
st+3t=6
t(s+3)/(s+3)=6/(s+3)
t=6/(s+3)

if you are required to solve for s then you are going to subtract 3t from both sides. you can factorise 6-3t .you will then divide both sides by t to isolate s.for this question you can only get s in terms of t.so:

st+3t-3t=6-3t
st/t=2(3-t)/t
s=2(3-t)/t

Alecsey [184]

Answer:

sqrt(x+7) - log(x+2)

Step-by-step explanation:

f(x) = sqrt(x+7)

g(x) log(x+2)

f(x) - g(x) = sqrt(x+7) - log(x+2)

F(4) =<br> If g(x) = 2, x =
Charra [1.4K]

Given:

The graph of two function f(x) and g(x).

To find:

The value of f(4) and the value of x if g(x)=2.

Solution:

In the given graph red curve is the graph of f(x) and the blue curve is the graph of g(x).

From the given graph it is clear that the value of the function f(x) at x=4 is -10. So,

f(4)=-10

From the given graph, it is clear that the value of function g(x) is 2 at x=0. So,

g(x)=2,x=0

Therefore, the value for the first blank is -10 and the value for the second blank is 0.
