Question

Thực hiện phép tính rồi phân tích kết quả ra thừa số nguyên tố:

a. (1000 + 1) : 11

b. 14² + 5² + 2²

c. 29. 31 + 144 : 12²

d. 333 : 3 + 225 : 15²

Answer 1

a)

\(=1001:11=91\)

b)

\(=196+25+4=200+25=225\)

c)

\(=29.31+144:144=899+1=900\)

d)

\(=111+225:225=111+1=112\)

Answer 2

Answer 3

91

225

112

Answer 4

a, (1000+1):11=1001:11=91

91=7.13

b, 14²+5²+2²=196+25+4=221+4=225

225=3².5²

c,29.31+144:12²=29.31+144:144=899+1

=900

900=2².3²5²

d, 333:3+225:15²=333:3+225:225=111+1

=112

112=2⁴.7

Answer 5

a)(1000+1):11=1001:11=91=7.13

b)14²+5²+2²=196+25+4=225=3².5²

c)29.31+144:12²=29.31+144:144=899+1=900=2².3².5²

d)333:3+225:15²=333:3+225:225=111+1=112=2⁴.7
