1) x² = 16

2)t² = 81
3)r² - 100 = 0
4)x² - 144 = 0
5)2s² = 50
6)4x² - 255 = 0
7)3h² - 147 = 0
8)(x-4)² = 169
9)(k + 7)² = 289
10)(2s - 1)² = 225

 

Answer:

1. x= 4 and -4

2. t= 9 and -9

3. r= 10 and -10

4. x= 12 and -12

5. s= 5 and -5

6. x=255/2 and -255/2

7.h= 7 and -7

8. x= -9 and 17

9.k=-24 and 10

10.s= -7 and 8
