what is the value of min(10, w) ?

For any integers x and y, min(x, y) and max(x, y) denote the minimum and the maximum of x and y, respectively. For example, min (5, 2) = 2 and max(5, 2) = 5. For the integer w, what is the value of min(10, w) ?

(1) w = max(20, z) for some integer z.
(2) w = max(10, w)

No, that does not work. Using 20/5 = 4, then what you would have, if the tens digit of 6¹ were the first member of the pattern, which is not the case, would be four times the entire pattern. 31795 31795 31795 31795 So the tens digit of 6²� would be 5. However the pattern starts at 6². So getti...

36 = 6² So 36¹� = 6²� Now look for a pattern to the tens digits of powers of 6. 6¹ = 6 Tens Digit: 0 6² = 36 Tens Digit: 3 6³ = 216 Tens Digit 1 6� = --96 Tens Digit 9 6� = --76 Tens Digit 7 6� = ---56 Tens Digit 5 6� = ----36 Tens Digit 3 OK. Now we are back to 3, and the pattern...

In many cases, the answers provide a 'clue' as to how you might go about solving the prompt (or they might be written in such a way as to allow you to avoid doing lots of calculati...

From ~7^1=~07, ~7^2=~49, ~7^3=~43, ~7^4=~01, the tens digit repeats 0-->4-->4-->0-->0. Then, from 7^381=7^(4(95)+1), the tens digit is same as ~7^1. Hence, it is 0. Hello Max, What's the difference between (7^4)^95.25 AND 7^(4(95)+1) ? This is to find the ten's digit of an odd number. Regards, MoM

Hello, Have given it a try. Please see if this is correct? 7 * 1 = 07 7*7 = 49 7*7*7 = 343 7*7*7*7 = 2401 7*7*7*7*7 = 16807 Hence, cyclicity of 7 is 4. Tens digit of an odd number - Number form when it ends with 1. (7*7*7*7 = 2401) So, it can be re-written as (7^4)^95.25 [ 381/4 = 95.25] The units d...
