if x8 = 20 then x = - eighth root of 20 or x = eighth root of 20
eighth root of 20 = 1.4542154....
Maybe you mean 8x = 20
If so Ln (8x) = Ln (20) => x Ln(8)= Ln(20) => x = Ln(20)/Ln(8) = 1.4406426...
how do you solve 8+x=x+8
x+8=20+12
2.45
0.05 = 1/20 (1/20)^6 = 1/64000000 = 1.5625 x 10^-8
x=15
how do you solve 8+x=x+8
Multiply 24 x 20 = 480, and 24 x 8 = 192, 480 + 192 = 680 - 8 = 672
8
8 = .40(x) 8(10/4) = .40x(10/4) 80/4 = x 20 = x x is 20, but you REALLY should start doing your homework and paying attention in class. Learning is important.
x4-8 = 0 x4 = 8 Eradicate the the power of 4 x = 1.681792831 Check: 1.6817928314 = 8.000000009 which is just about correct.
4 x 12 + 4 x 8 = 4 x (12 + 8) = 4 x 20 = 80
-8
The answers is a question of "powers" - in this case Cubes (3rd power) 1728 = 12 cubed (12 x 12 x 12) 512 = 8 cubed (8 x 8 x 8) 8000 = 20 cubed (20 x 20 x 20) That makes the answer to this question 1331 - with regards to the number set I was given to solve for. 1331 = 11 cubed (11 x 11 x 11) Sarcasual
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
x+8=20+12
How do you solve 4y plus x equals 8
It could be a mathematical formula. If you equate it to a value, you can solve for X, if you want. For example if (X+5)/8 = 20, then X = 8x20-5, which equals 155. Now, if you mean X+5/8, then if you set it equal to 20 you get X = 20-5/8, which equals 19 3/8 or 19.375. All by itself though, X plus 5 over 8 could be anything. Or nothing.
