Fractions and decimals cannot be integers. whole, natural numbers are integers (ex. 5,6,7).

2n-7/3 = 15 solve for n

WITCHER [35]

$2n- \frac{7}{3} =15$
$2n- \frac{7}{3} =15$ common denominator is 3
$3(2n- \frac{7}{3} )=3*15$ distributhing 3 through parantheses
$3*2n- \frac{3*7}{3}=3*15$
$3*2n-7=3*15$
$6n-7=45$ add7
$6n=45+7$
$6n=52$ divide by 6
$n= \frac{52}{6}$ simplify
$n=8 \frac{2}{3}$ ⇒ $\frac{26}{3}$

Explain how you can find any power of 1

My name is Ann [436]

$\bf \begin{array}{llll}
1^2\implies 1\cdot 1\implies &1\\\\
1^3\implies 1\cdot 1\cdot 1\implies &1\\\\
1^{100}\implies \stackrel{\textit{100 times}}{1\cdot 1...}\implies &1\\\\
1^{1000000}\implies \stackrel{\textit{a million times}}{1\cdot 1....}\implies &1\\\\
1^{x}\qquad \{x|~~x\in \mathbb{Z}\}\implies &1
\end{array}$
