<h2>Answer</h2>

Janice convert a mixed number to the wrong improper fraction

<h2>Explanation</h2>

To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the result to the numerator of the fraction; while keeping the denominator of the fraction as the denominator of the improper fraction.

Let's convert our mixed numbers to improper fractions:

To convert 10\frac{5}{6} we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:

10\frac{5}{6} =\frac{(10*6)+5}{6} =\frac{60+5}{6} =\frac{65}{6}

Now let's convert 1\frac{2}{3}:

1\frac{2}{3}=\frac{(1*3)+2}{3} =\frac{3+2}{3} =\frac{5}{3}

Notice that Janice converted 1\frac{2}{3} as \frac{5}{2}, which is incorrect.

Since 1\frac{2}{3} =\frac{5}{3}, we can conclude that Janice convert a mixed number to the wrong improper fraction.

Find the missing exponent. Set up an equation and solve. : x^4·x^n = x^5
algol [13]
Remember
(x^m)(x^n)=x^(m+n)
and
if a^m=a^n, where a=a then n=m


(x^4)(x^n)=x^5
(x^4)(x^n)=x^(4+n)
x^(4+n)=x^5
therefor
4+n=5
minus 4
n=1
