Question

simply:49×z-³/7-³×10×z-5(z#0)​

Answer 1

Answer:

$= \frac{49 \times {z}^{ - 3} }{ {7}^{ - 3} \times 10 \times {z}^{5} } \\ = multiply \: numerator \: and \: denominator \: with \: {z}^{5} \\ = \frac{49 \times {z}^{ - 3 + 5} }{ {7}^{ - 3} \times 10 \times {z}^{ - 5 + 5} } = \frac{49 \times {z}^{2} }{ \frac{1}{7 {}^{3} } \times 10} \\ = \frac{343 \times 49 \times {z}^{2} }{10} or \: \frac{ {7}^{3} \times {7}^{2} \times {z}^{2} }{10} \\ = \frac{16807 \times {z}^{2} }{10} or \: \frac{ {7}^{5} \times {z}^{2} }{10} \\ = 1680.7 \times {z}^{2} \: or \: \frac{ {7}^{5} \times {z}^{2} }{10} \\ \\ hope \: its \: helpful \: to \: you \:$
