Question

A=2 la puterea 2018*5la puterea2019+1 B=2la puterea 2016+5 la puterea 2018+1 afla A+B si A-B

Answer 1

$A=\left(2^{2018\cdot \:5}\right)^{2019+1}=2^{2018\cdot \:5\left(2019+1\right)}=2^{20381800}$

$B=\left(2^{2016+5}\right)^{2018+1}=2^{\left(2016+5\right)\left(2018+1\right)}=2^{4080399}$

$A+B = 2^{20381800}+2^{4080399}$

$A-B = 2^{20381800}-2^{4080399}$
