The square root of anything to an even power is that thing to half the power. √(5x^13) = √(x^12 5x) = √(x^12) √(5x) = x^6 √(5x) But is that really any simpler?
x + 5x + 5 = 47 6x = 42 x = 7 x + 1 = 8
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
If: 3x-7 = 5x+13 Then: x = -10
5x - 4 = 47 Add '4' to both sides 5x - 4 + 4 = 47 + 4 5x = 51 Divide both sides by '5' 5x/5 = 51/5 x = 51/5 = 10 1/5 = 10.2

x=6
5x + 2 < 47 subtract 2 from both sides: 5x < 45 divide both sides by 5: x < 9.
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
If: 3x-7 = 5x+13 Then: x = -10

8(1+5x) +5 = 13+5x => 8+40x + 5 = 13 +5x => 13+40x = 13+5x => 13-13+40x = 13-13+5x => 40x = 5x => 40x - 5x = 0 => 35x = 0 => 35x/35 = 0/35 => x = 0
