Answer 1

Răspuns:

a) 64 + 36 = 100 ; 1000 - 100 = 900

b) 32 × 10 = 320 ; 32 × 1000 = 32000

c) 640 - 112 = 528 ; 625 × 2 + 45 = 1295

d) 36 × 64 = 2304 ; 16 × 100 × 243 = 388800

e) 2 + 6 + 64 × 5 = 328 ; 10005 - 408 + 830 = 10427

f) 4 × 500 + 100000 = 102000 ; (243 + 121) × 10 - 19 = 3640 - 19 = 3621

Answer 2

Explicație pas cu pas:

ღSalutare!ღ

a) 4³+36=64+36=100

1 000-10²=1 000-100=900

b) 2⁵×10=32×10=320

32×10³=32×1 000=32 000

c) 640-7×2⁴=640-7×16=640-112=528

5⁴×2+45=625×2+45=1 250+45=1 295

d) 6²×2⁶=36×64=2 304

2⁴×10²×3⁵=16×100×243=1 600×243=388 800

e) 2×3⁰+3×2¹+4³×5=2×1+3×2+64×5=2+6+320=8+320=328

10⁴×5¹-2³×20²+830=10 000×5-8×400+830=50 000-3 200+830=46 800+830=47 630

f) 4×(8³-12)+10⁵=4×(512-12)+100 000=4×500+100 000=2 000+100 000=102 000

(3⁵+11²)×10-19=(243+121)×10-19=364×10-19=3 640-19=3 621

Succes!;)
