Well... you never finished your sentence so I'll fill in the blank. Sorry if its wrong. And he wants to see how much money he needs left. He need 117 more dollars
For this case we have that by definition of properties of powers and roots, it is fulfilled that:
\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}
n
a

=a

So:
\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}

So, we have to:
\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {1} {8} x}

Bernardo travels the same distance at 25mph as he does at 50mph. However, since 25mph is only half of 50 mph, he must travel twice as long at 25mph. If you call the time he traveled 50mph "t", then
<span>t+2t=3 </span>
<span>3t=3 </span>
<span>t=1 </span>
<span>This means he traveled 1 hour at 50mph. In this time, he traveled 50 miles. He traveled the same distance at 25mph, so his total distance was </span>
<span>50miles+50miles=100miles </span>
<span>so the round trip was 100 miles.</span>
To simplify you must factor the polynomials first.
