Calculation: (a ^ 3 · B ^ m) 3 · B ^ 2 (2) 2 ^ 4 + 4 ^ 5 × (- 0.125) ^ 4 It's all about process... Online===


(a^3·b^m)^3·b^2
=a^9*b^(3m)*b^2
=a^9*b^(3m+2)
2^4+4^5×(-0.125)^4
=2^4+4^5×(1/8)^4
=2^4+2^10/2^12
=16+1/4
=16 and 1 / 4

"At least one of any three consecutive natural numbers is even." is that right? Please use the drawer principle to explain


Hello, that's right
We can regard odd and even numbers as two drawers. In this way, if three continuous natural numbers are put in these two drawers, there must be two numbers in one drawer. Therefore, at least one of any three continuous natural numbers is even



Fill the 9 natural numbers 1-9 in the table below, so that each horizontal line, vertical line, oblique line and 15 are how to think?
The steps I want to think about~


7, 8, 9 in 1-9 can't meet each other, so fill in the second row, the second row, the first row, the third row, the third row, the fifth row, the most special row, the middle 7 can be with 2, 6, 3, 58 can be with 1, 6, 2, 5, 3, 49 can be with 1, 5, 2, 4, the four corners should be with three groups to form 15, so row 8 is in the third row



Fill the 9 natural numbers 1-9 in the table below so that the sum of each horizontal, vertical, oblique line is 15


438
951
276



Fill nine different natural numbers in the following boxes to make the product of the three numbers horizontal, vertical and diagonal equal


2 64 32
256 16 1
8 4 128



From the thirteen natural numbers 1-13, choose twelve and fill them in the small squares in the right figure. Make the sum of four numbers in each horizontal row equal and the sum of three numbers in each vertical column equal. Then what is the sum of the horizontal and vertical columns? (4 * 3 small squares)


The horizontal sum is 28, and the vertical sum is 21



If in 7 consecutive even numbers, the largest number is exactly 3 times the smallest number, then the largest number is equal to______ .


Let seven consecutive even numbers be n-6, n-4, n-2, N, N + 2, N + 4, N + 6 in turn, then from the meaning of the title, we can see that N + 6 = 3 (n-6), and the solution is n = 12. So the largest even number is n + 6 = 18



In three consecutive even numbers, if the smallest even number is 2n + 4 (n is an integer), what is the largest even number? When n is equal to 8, what is the middle number?


Two consecutive even numbers differ by 2
The smallest even number is 2n + 4
So the maximum is (2n + 4) + 2 + 2 = 2n + 8
