Question

Daca 3,2<a<7,2 si 1,3<b<3,7, atunci determinati intre ce numere este cuprinsa expresia:
a)2a+3a+23,456
b)a×b-2,123
c)a la puterea 2+b la puterea 2
d)5a-2b+a la puterea 2
VA ROG, E URGENT!!!!

Answer 1

A = 4
B = 2
a) 2×4+3×4+23,456
= 8+18+233,456
= 26+23,456
= 49,456

b) 4×2-2,123
= 8-2,123
= 6,123

c) 4 la puterea 2 + 2 la puterea 2
= 16+4
= 20

d) 5×4-2×2+4 la puterea 2
= 20-4+16
= 16+16
= 32
