8. In preparation for a wedding, Aiden bought 60 candles. He paid \( \$ 0.37 \) for each candle. His sister bought 170 candles at the same price. How much more money, in dollars, did Aiden's sister spend?

Simplify the expression and write the answer with positive exponents only. \( \left(\frac{x^{2}}{z^{4}}\right)^{-5}\left(\frac{x^{2}}{z^{4}}\right)^{5} \)

COMPLEME

Factor the given binomial completely. \[ 4 x^{2}-49 \]

Consider the following value. \[ \mathrm{E} 0 \mathrm{~B} 6_{\text {sixteen }} \] Convert the above value to its equivalent decimal (base 10) representation. E0B6 \( 6_{\text {sixteen }}=\square \)
