Express 2021 as a product of its prime factors. (n) Given that a and b are whole numbers such that a is less than b and a x b = 2021,
write down all the possible pairs (a, b).

Product of its prime factors are;

43 * 47

Possible pairs are;

43 * 47

1 * 2021

Step-by-step explanation:

2021 as a product of its prime factors is;

43 * 47

Possible pairs of 2021 are;

(43.47)

(1, 2021)

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)
