Word problem: Sachin’s office is 11.37km away from his house. He covers 9.245km by bus and rest by walking. How much distance does he cover by walking?

(I only need the answer and how to do it ,PLS PLS PLS HELP I REALLY Need It PLS HELP

Step-by-step explanation:

=2* ( l+b )

=2* ( 11.37+9.245 )

=2* 20.595

=41.19

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
