Step-by-step explanation:

Given expression:

        (√4)⁻⁷  x (√2)⁻⁵

To solve this problem, we are going to use some rules of exponent;

      (√4)⁻⁷  x (√2)⁻⁵  

               4  = 2²

 =  (√2²)⁻⁷  x  (√2)⁻⁵

            √x² = x

= (  2) ⁻⁷  x (2)⁻⁵

=  2⁻⁷  x  2  

          aˣ  x aⁿ = aˣ⁺ⁿ

 So;

                  2⁻⁷  x  2   = 2  

                                      = 2  

                                      = 2

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
