(x to the power of - 1) to the power of 2 × x to the power of - 2 △ x to the power of 0

(x to the power of - 1) to the power of 2 × x to the power of - 2 △ x to the power of 0

The original formula = the - 2 power of X × the - 2 power of X △ the 0 power of X
=The - 2-2-0 power of X
=The fourth power of X
