Art [367]

Let x be the number of households with TV.

So .68x would be the number of households with cable.

If 8000 were added to the above number, it would be equal to 67,600,000.

Thus we have our equation:

.68x + 8000 = 67600000

Solving for x:

.68x = 67592000

x = 99,400,000

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

Convert the expressions from radical to exponent form.

$9 \sqrt[4]{ {t}^{3} } \times 7 \sqrt[3]{ {t}^{2} } \\ 9( {t}^{ \frac{3}{4} } ) \times 7( {t}^{ \frac{2}{3} } )$

Simplify the expression by multiplying.

$63( {t}^{ \frac{3}{4} } \times {t}^{ \frac{2}{3} } ) = 63( {t}^{ \frac{3}{4}+\frac{2}{3} } ) \\ 63( {t}^{ \frac{9}{12} + \frac{8}{12} } ) \\ 63( {t}^{ \frac{17}{12} } )Answer[tex] \large \boxed {63 {t}^{ \frac{17}{12} } }$
