Question

find the following products and verify the results in each case for x=2,y=1,z=1​

Answer 1

Step-by-step explanation:

$\frac{3}{4} \times 5 \times \frac{ - 8}{150} ( {x}^{2} y \times xyz \times {z}^{2} ) \\ = \frac{ - 2}{10} {x}^{3} {y}^{2} {z}^{4}$

verification

$rhs\\ \frac{ - 2}{10} \times 8 \times 1 \times 1 \\ = \frac{ - 8}{5} \\ lhs \\ \frac{3}{4} \times 4 \times 5 \times 2 \times \frac{ - 8}{150} \times 1 \\ = \frac{ - 8}{5} \\ therefore \: rhs = lhs$
