Question

Match each equation with a value of x that satisfies it. ​

Answer 1

a) x =18

b) x=2

c) x=3

Explanation:

Step(i):-

a)

Given that
`(x-2)^{(1)/(4) }`

put x = 18

⇒
`(18-2)^{(1)/(4) } = (2^(4) )^{(1)/(4) } = 2`

`(x-2)^{(1)/(4) }` =2

b)

put x= 2

`(1-x)^{(1)/(3) } = (1-2)^{(1)/(3) } = (-1)^{(1)/(3) } = -1`

`(1-x)^{(1)/(3) } = -1`

c)

put x=3

`\sqrt{x^(2) +7} = \sqrt{3^(2) +7} = √(16) = 4`

`\sqrt{x^(2) +7}= 4`
