1.- Find the prime factors of 196

                              196  2

                               98   2

                               49   7

                                 7    7

                                 1

Express 196 as a composition of prime factors

        196 = 2²7²

2.- Express the root as exponents

                            =

                                              = 2²/² 7 ²/² m¹²/² n⁴/²

Simplify                                 = 2 7 m⁶ n²

Result                                     = 14m⁶n²                                            

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
