Step-by-step explanation:

Data

Process

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                                            

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

you already gave the answer
