(1) 32
(2) 52
(3) (−4)2
(4) (−2)2
(5) (−52)2
Find the squares of:
(1) 32
(2) 52
(3) (−4)2
(4) (−2)2
(5) (−52)2
Open in App
Solution
(1) 32 = 3 × 3 = 9
(2) 52 = 5 × 5 = 25
(3) (−4)2 = (−4) × (−4) = +16
(4) (−2)2 = (−2) × (−2) = +4
(5) (−52)2 = (−52)× (−52) = (−25)× (−25) = +625
(1) 32 = 3 × 3 = 9
(2) 52 = 5 × 5 = 25
(3) (−4)2 = (−4) × (−4) = +16
(4) (−2)2 = (−2) × (−2) = +4
(5) (−52)2 = (−52)× (−52) = (−25)× (−25) = +625
