va rog urgent repede !!!​

Answer 1

a) (7-3)^3= 4^3=4x4x4= 16x4=64
b) (2+3)^2= 5^2= 5x5= 25
c) 12^2–5^2= 144–25= 119
d) 40^2+30^2= 1600+900= 2500
e) 50^2–30^2= 2500–900= 1600
f)2^4+3^2 x5^0= 16+ 9x1=16+9=25
g) 5^2–3^2+4^2= 25–9+16=16+16=32
h) 15^2–2^2x3^2= 225–4x9=225–36=189
i) 5^2+2x5x3+3^2=25+30+9=64

Sper sa fie totul corect!
