Số 986 nha em .
Find all natural numbers having two digit , knowing that twice the units digit 1 more than the ten digit , and if we write that two digits in reverse order, we get a new number which is 27 less than the old one
Tell the numbers to find are \(\overline{ab}\)
\(\Rightarrow\left\{{}\begin{matrix}2b-a=1\\\overline{ab}-\overline{ba}=27\end{matrix}\right.\)
=> 10a + b - 10b - a = 27
=> 9a - 9b = 27
=> a-b = 3
=> a = b + 3
=> 2b - 1 = b+3
=> 2b - b = 3 + 1
=> b = 4
=> a = \(2\cdot4-1=7\)
So he number to find is 74

Answer:
How many natural numbers having three digits such thatthe tens digit squared equals the product of other digits and the differencebetween that number and its reversed order is 495?
using each of a digit 3,4,5 and 6 exactly once to form two 2 digit numbers .what is the different between the largest possible product and the smallest possible product of two such number
Hai số lớn nhất là 65; 64
Hai số nhỏ nhất là 34 ; 35
Hiệu là : 65 x 64 - 35 x 34 = 2970
nếu đúng tk cho mk nha
34; 35; 36; 43; 45; 46; 53; 54; 56; 63; 64; 65.
The largest number is 65.
The smallest number is 34.
Using each of the digits 3, 4, 5 and 6 exactly once to form two 2 - digit numbers. What is the difference between the largest possible product and the smallest possible product of two such numbers?
sai rồi, tớ cũng nghĩ thế nhưng ghi thi người ta bảo sai
giải
họ hỏi là hiệu giữa số bé nhất và số nhỏ nhất lập được:
số lớn nhất lập được : 65
số bé nhất lập được: 34
hiệu : 65 - 34 = 32
nhé !
