what is the 8th term of (2x+2y) to the 10th power?
970351
The formula is 10C7 (2x)^3 (2y)^7\n\nThis comes out 122880x^3y^7

same thing as (8x^2+2x-2)^(3/2), right?\nso add one to the power\nmultiply by the inverse of that power\nand divide by the derivative of what's in the parenthesis on the left\ngot it?

The last digit of the powers of 2 follow a definite pattern, which is 2, 4, 8, 6, and then again 2, 4, 8, 6 etc. \n\nTo find the answer, simply take 51 mod 4, (which happens to be 3), and the third number in the list is 8. The answer is therefore 8.

(10x+8) - (5x+4)\n= 10x - 5x +8 -4\n= 5x + 4

6x+2y=10\nsubract 6x fro both sides\n2y=-2x+10\ndivide both sides by 2\ny=-x+5

i know how 2 do this.\n4x+2y=2\n x-2y=8\n---------\n5x   =10\n5x=10\nx=10/5\nx=2.\nsubstitute x=2 in any1 of the equations.\nlet us take x-2y=8.\n  2-2y=8\n  -2y=8-2\n  -2y=6\n    y=6/-2\n    y=-3.\n therefore ur x=2 nd y=-3.

2[w+ {2w+8}]= 64\n3w+8 = 32\nw= 8 \nyour are right

Simply put, multiply the number by some power of 10 to get one digit to the left of the decimal.\n0.08277 = 8.277 * 10^-2\n(Eight point two seven seven times 10 to the negative second power)

It is based on powers of 2.\n\ni.e. 2 ^ 10 = 1024

8x^2y\n\nas long as the x's and the y's are the same in both terms, you can just add them up...\n\nboth terms have x^2 and both terms have y and no other variables, so just add them up\n \n(3+5)x^2y = 8x^2y
