2/3x=4/6x
1/2x=3/6x
4/6x-5=3/6x-3
add 5 to both sides
4/6x=3/6x+2
subtract 3/6x from both sides
1/6x=2
multiply both sides by 6
x=12

What is the simplify of the expression where possible (r3s2t)4
Mandarinka [93]

Answer:

The simplification of the given expression  (r3s2t)4 is:

r¹²s⁸t⁴

Step-by-step explanation:

Given expression:

(r³s²t)⁴

power of '4' on the whole term will be applied to individual terms after we open the brackets. In this case the power on the whole term will be multiplied to the power of each individual term:

= (r³)⁴(s²)⁴(t1)⁴

= r³ˣ⁴ s²ˣ⁴ t¹ˣ⁴

= r¹²s⁸t⁴
