Which expression is equivalent to the given expression? Assume the denominator does not equal zero.

Fudgin [204]

Answer:

$4{J^{9} } {K^{14} }$

Step-by-step explanation:

$\frac{8}{2} \frac{J^{4} }{J^{5} } \frac{K^{8} }{K^{6} }$

$\frac{8}{2}$ = 4

$\frac{J^{4} }{J^{5} }$ = $J^{4+5}$ = $J^{9}$

$\frac{K^{8} }{K^{6} }$ = $K^{8+6}$ = $K^{14}$

melamori03 [73]

Answer:

The given proportion is

$\frac{14}{x}=\frac{56}{16}\\\\14 \times 16=56\times x\\\\x=\frac{14 \times 16}{56}\\\\x=\frac{16}{4}\\\\x=4$

Substitute , x=4 in the equation

$\frac{14}{4}=\frac{56}{16}\\\\56 \times 4=14 \times 16\\\\224=224$

Option D

Because if you substitute 4 into the equation for x and cross multiply, you get 224 = 224.
