Question

Va rog ajutati-ma la ex 6 și 9!!! va dau coroana!!​

Answer 1

Răspuns:

A=(4·8-4·1):4+(8+2)²:5

A=(32-4):4+10²:5

A=28:4+100:5

A=7+20

A=27

B=6+2·(14-1)

B=6+2·13

B=32

27=3³

32=2⁵

cmmmc (27; 46) = 2⁵ × 3³ = 864

cmmdc (27; 32) = 1

____________

A=[(6⁵:6²-2³)-5²]:3

A=[(6³-2³)-5²]:3

a=[(216-8)-25]:3

A=183:3

A=61

B=(12-3)·10

B=9·10

B=90

cmmmc (61; 90) = 2 × 3² × 5 × 61 = 5490

cmmdc (61; 90) = 1
