Question

REPEDE! Dau coroana .​

Answer 1

x=$(3^{2})^{40}$:$3^{76}-10$

x=$3^{2*40}$:3^{76}-10

x=$3^{80}$:3^{76}-10

x=$3^{80-76}-10$

x=$3^{16} -10$

y=$(2^{40}+2^{41}+2^{42} ):2^{38} +2020^{0}$

y=($2*2^{40}*2^{41}$) $:2^{38} +1$

y=$2^{1+40+41} :2^{38} +1$

y=$2^{82} :2^{38} +1$

y=$2^{82-38} +1$

y=$2^{44}+1$

ma=\frac{x+y}{2}

$ma=\frac{(3^{16}-10)+(2^{44}+1)}{2}$
