Answer 1

a)

$x + 1 = \sqrt{36}$

$x + 1 = 6$

$x = 5$

b)

$x - 2 = \sqrt{9}$

$x - 2 = 3$

$x = 5$

c)

$2x + 3 = \sqrt{49}$

$2x + 3 = 7$

$2x = 4$

$x = 2$

d)

$3x - 1 = \sqrt{81}$

$3x - 1 = 9$

$3x = 10$

$x = \frac{10}{3}$

e)

$x + 5 = \sqrt{36}$

$x + 5 = 6$

$x = 1$

f)

$x - 2 = \sqrt{16}$

$x - 2 = 4$

$x = 6$
