x=\sqrt{70}, y =\sqrt{21}, z=\sqrt{30}

Solution:

Given c = 3 and d = 10 – 3 = 7

<u>To find the value of y:</u>

y^2= 3\times 7

y^2= 21

Taking square root on both sides of the equation.

y=\sqrt{21}

<u>To find the value of x:</u>

x^2=7\times10

x^2=70

Taking square root on both sides of the equation.

x=\sqrt{70}

<u>To find the value of z:</u>

z^2=3\times10

z^2=30

Taking square root on both sides of the equation.

z=\sqrt{30}

Hence the value of x=\sqrt{70}, y =\sqrt{21}, z=\sqrt{30}.
