Question

A=(25^3)^9÷(4^2+3^2)^26-(2017^0+0^2017+1^2017)^4

Answer 1

$A=\left(25^3\right)^9\div \left(4^2+3^2\right)^{26}-\left(2017^0+0^{2017}+1^{2017}\right)^4=15625^9\div \left(4^2+3^2\right)^{26}-\left(2017^0+0^{2017}+1^{2017}\right)^4=15625^9\div \:25^{26}-\left(2017^0+0^{2017}+1^{2017}\right)^4=15625^9\div \:25^{26}-2^4=25-16=9$
