The product of a 4-digit multiplicand and a 1-digit multiplier can have either 4 or 5 digits. If the 4-digit number is multiplied by a multiplier of 1 to 9, the product will typically have 4 digits. However, if the multiplicand is multiplied by 10 (the maximum value for a 1-digit number), the product can reach a maximum of 5 digits. Thus, the product can range from 4 to 5 digits, depending on the specific numbers involved.

The greatest nine-digit number is 999,999,999. This is achieved by having all nine digits as the highest single-digit number, which is 9. Any variation with lower digits would result in a smaller number.
The largest two-digit number is 99. When multiplied by itself, (99 \times 99 = 9801), which is a four-digit number. Therefore, 99 is the largest two-digit number that can be squared to yield a four-digit result.
Find a four digit number whose digits will be reversed when multiplied by nine?
The number is 21978. 21978 when multiplied by 4 which gives the result 87912 which is in reverse order.
Six.
No, reversing the order of the digits of a two-digit prime number does not always result in a prime number.

A two digit number whose two digits added together equal 42 and multiplied together equal 82
The product of 12345678910 multiplied by 12345678910 is 152415567732446676100. This result is obtained by multiplying each digit in the first number by each digit in the second number, following the rules of multiplication. The final answer is a 20-digit number, calculated by adding the products of each combination of digits.
Oh honey, that's a big number you got there! The product of 987654321 multiplied by 987654321 is 975461057789971041. So, there you have it, a whole lotta digits to wrap your head around. Hope you brought your calculator for that one!
