$4(n+1)+n=49\\
4n+4+n=49\\
5n=45\\
n=9\\
n+1=10
$

These numbers are 9 and 10.

Answer:

${n}^{1\frac{1}{2}}{p}^{2}$

Step-by-step explanation:

According to the Definition of Rational Exponents, use this formula to rewrite this as an exponential expression:

$a^{\frac{m}{n}} = \sqrt[n]{a}^{m}$

NOTE: Since we have exponents in our radical, we have to multiply all exponents by one-half, since raising something to its <em>half power</em> is the exact same as taking the <em>square root</em> of something:

$[{n}^{3}{p}^{4}]^{\frac{1}{2}} = {n}^{1\frac{1}{2}}{p}^{2}$

* Do not forget to remove the radical in the beginning because you are once again, rewriting this as an exponential expression.
