Question

Solve 3the square root of x minus three) – 5 = 16

x = 5

x = 19

x = 52

x = 67

Answer 1

sqrt(x - 3) - 5 = 16
sqrt(x - 3) = 21
now square both sides

Answer 2

how did you get rid of the cubed root? \[\sqrt[3]{x-3} - 5 = 16\]

Answer 3

oh - missed the 3
sorry

Answer 4

r u sure thats right

not 3 times the square root of x - 3?

Answer 5

it probably is three times the square root, im sorry

Answer 6

so squared it would be 3(x-3) = 441?

Answer 7

lol ok

so
3 sqrt(x - 3) = 21
sqt(x - 3) = 21/3 = 7
x- 3 = 49

Answer 8

so x= 52?

Answer 9

yep

Answer 10

Answer 11

yw

Answer 12

the aim is to isolate the square root bit then square both sides
