    480 : [ 75 + ( 7² – 2³ x 3 ) : 5 ] + 2021^0
    = 480 :[ 75 + ( 49 – 8  x 3 ) : 5 ] +1
    = 480 :[ 75 + 25 : 5 ] + 1
    = 480:80 + 1
    = 7

    480 : [ 75 + ( $7^{2}$ – $2^{3}$ * 3 ) : 5 ] + $2021^{0}$ 
    = 480 : [ 75 + ( 49 – 8 * 3 ) : 5 ] + 1
    = 480 : [ 75 + ( 49 – 24 ) : 5 ] + 1
    = 480 : [ 75 + 25 : 5 ] + 1
    = 480 : [ 75 + 5 ] + 1
    = 480 : 80 + 1
    = 6 + 1
    = 7
