Question

Find the value of x,y and z

Answer 1

`x=√(70), y =√(21), z=√(30)`

Solution:

Given c = 3 and d = 10 – 3 = 7

To find the value of y:

`y^2= 3* 7`

`y^2= 21`

Taking square root on both sides of the equation.

`y=√(21)`

To find the value of x:

`x^2=7*10`

`x^2=70`

Taking square root on both sides of the equation.

`x=√(70)`

To find the value of z:

`z^2=3*10`

`z^2=30`

Taking square root on both sides of the equation.

`z=√(30)`

Hence the value of
`x=√(70), y =√(21), z=√(30)`.
