(3x)(3x)(x)(x) = (5x)(x)(x) 9x^4=5x^3 divide by x^3 9x = 5 x = 5/9
(3)(2)(2)5x=60 12(5x)=60 12(5x)/12=60/12 5x=5 x=1
10x2
it means "five times"; for example if x = 1 then 5x is 5; if x= 2 then 5x = 10, etc.
(5x)2 = 25x2.
When x equals 8, the value of 5x would be 5 times 8, which is 40.
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
125x3, because you have to times the x too. So it's like (5x)(5x)(5x) and what do you get? 125x3!!
