Question

9. Efectuați: XYZ a) 16X'Y:(-2XY); b)-6,4Y'Z':0,4YZ; c) 2√3x²z²:√3xz²; d) 7X²Y³Z³" ​

Answer 1

$16xy \div ( - 2xy) = - 8$

$- 6.4yz \div 0.4yz = - 16 {y}^{2} {z}^{2}$

$2 \sqrt{3} {x}^{2} {z}^{2} \div \sqrt{3}x {z}^{2} = 2 {x}^{3} {z}^{4}$

$7 {x}^{2}{y}^{3} {z}^{3} = 7 \times x \times x \times y \times y \times y \times z \times z \times z$
