Question

81p² + 5 = 41
how do I solve by square roots

​

Answer 1

p = ±
`(2)/(3)`

Explanation:

Given

81p² + 5 = 41 ( subtract 5 from both sides )

81p² = 36 ( divide both sides by 81 )

p² =
`(36)/(81)` ( take the square root of both sides )

p = ±
`\sqrt{(36)/(81) }`

= ±
`(√(36) )/(√(81) )` = ±
`(6)/(9)` = ±
`(2)/(3)`
