Question

6. Solve each equation by finding square roots. If the equation has no real-number solution, write no

solution.
64b2 = 16​

Answer 1

b = (1/2) or, b = -(1/2)

Explanation:

Here, the given equation is
`64 * b^(2)  = 16`

or, by transposing 64 on the other side, we get
`b^(2)  = (16)/(64)  </p><p>= (1)/(4)`

Now, taking root both the sides, we get

`b = \sqrt{(1)/(4) }`

⇒
`b = +((1)/(2))  \\b = -((1)/(2))`

Both values of b are possible here.
