2zx2y=18 where x=1,z=y

Bad White [126]

$\huge \bf༆ Answer ༄$

Let's plug the given values and find value of y ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2zx2y = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2 \times y \times 1 \times 2 \times y = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:4 {y}^{2} = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:{y}^{2} = \dfrac{18}{4}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y {}^{2} = 4.5$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = \sqrt{4.5}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = \sqrt{9 \times 0.5}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = 3 \sqrt{ \frac{5}{10} }$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 \sqrt{ \frac{1}{2} }$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{3}{ \sqrt{2} }$

or, you can further simplify it to ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2.12 \: \: (upto \: \: two \: decimals)$
