It is so very simple and quick to get the answer, especially since you can use the calculator that comes with your computer. But since you are not able to do so, the answer is 27,745.
The Expanded Notation of 895 = (8 x 102) + (9 x 101) + (5 x 100)
4/5 of 895 is 716.
40 percent of 895 is 358.
well that's an easy one 328 = CCCXXVIII 623 = DCXXIII 895 = DCCCXCV (fyi the dots are there for no reason) sorry i can't find one that would translate all 9 digits but: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . _ _ _ three hundred and twenty eight million = |X|X|X| XXVIII M quite literally means: 300mil 28 thou then we have 623,000 = DCXXIII M and finally 895 which is very easy 895 = XCM (5 before 100 before 1000) . . . . . . . . . . . . . . . . . . . . . . _ _ _ so all together that makes |X|X|X| XXVIII MDC XXIII M hope i helped! (btw this is estimated my source is below) http://www.roman-Britain.org/numerals.htm it was easy but I'm used to doing sums like that
31 x 49 = 1519
895 x 509 = 455,555.
The Expanded Notation of 895 = (8 x 102) + (9 x 101) + (5 x 100)
9 x 895 = (9 x 900) - (9 x 5) = 8100 - 45 = 8055
2.3% of 895= 2.3% * 895= 0.023 * 895= 20.585
They are: 1, 5, 179 and 895
895 mg = 0.895 g
895 kilometers = 556.1 miles
4/5 of 895 is 716.
40 percent of 895 is 358.
1, 5, 179, 895
x6 + 9= x6 - (-9) since i2 = -1= (x3)2 - 9i2 factor the difference of two squares= (x3 + 3i)(x3 - 3i) since 3 = (31/3)3 and -i = i3 we can write:= [x3 - (31/3)3i3] [x3 + (31/3)3i3]= [x3 - (31/3i)3] [x3 + (31/3i)3] factor the sum and the difference of two cubes= [(x - 31/3i)(x2 + 31/3ix + (31/3)2i2)] [(x + 31/3i)(x2 - 31/3ix + (31/3)2i2)]= [(x - 31/3i)(x2 + 31/3ix - (31/3)2)][(x + 31/3i)(x2 - 31/3ix - (31/3)2)]Thus, we have two factors (x - 31/3i) and (x + 31/3i),so let's find four othersAdd and subtract x2/4 to both trinomials[x2 - x2/4 + (x/2)2 + 31/3ix - (31/3)2] [x2 - x2/4 + (x/2)2 - 31/3ix - (32/3)2] combine and factor -1= {3x2/4 - [((x/2)i))2 - 31/3ix + (31/3)2]}{3x2/4 - [((x/2)i))2 + 31/3ix + (32/3)2]} write the difference of the two squares= {((3)1/2x/2))2 - [(x/2)i - 31/3]2}{((3)1/2x/2))2 - [(x/2)i + 32/3]2]} factor the difference of two squares= {[(31/2/2)x - ((1/2)i)x - 31/3)] [((31/2/2)x + ((1/2)i)x - 31/3)]} {[((31/2/2)x) - (((1/2)i)x + 31/3)] [((31/2/2)x) + ((1/2)i)x + 31/3)]}= {[(31/2/2)x - ((1/2)i)x + 31/3)] [((31/2/2)x + ((1/2)i)x - 31/3)]} {[((31/2/2)x) - ((1/2)i)x - 31/3)] [((31/2/2)x) + ((1/2)i)x + 31/3)]} simplify= {[((31/2 - i)/2))x + 31/3)] [((31/2 + i)/2))x - 31/3)]} {[((31/2 - i)/2))x - 31/3)] [((31/2+ i)/2))x + 31/3)]}so we have the 6 linear factors of x2 + 9.1) (x - 31/3i)2) (x + 31/3i)3) [((31/2 - i)/2))x + 31/3)]4) [((31/2 + i)/2))x - 31/3)]5) [((31/2 - i)/2))x - 31/3)]6) [((31/2+ i)/2))x + 31/3)]Check: Multiply:[(1)(2)][(3)(5)][(4)(6)]A) (x - 31/3i)(x + 31/3i) = x +(31/3)2B) [((31/2 - i)/2))x + 31/3)] [((31/2 - i)/2))x - 31/3)] = [(1 - (31/2)i)/2]x2 - (31/3)2C) [((31/2 + i)/2))x - 31/3)][((31/2+ i)/2))x + 31/3)] = [(1 + (31/2)i)/2]x2 - (31/3)2Multiply B) and C) and you'll get x4 - (31/3)2x2 + (31/3)4Now you have:[x +(31/3)2][x4 - (31/3)2x2 + (31/3)4] = x6 + 9
1 x 31, 2 x 31/2 , 3 x 31/3 etc. 31 is a prime number.
