Question

Efectuati:a){2^0+(-3}^2x(-4+6)^5x(8-10)^6-2^10x(-1+3)^3
b)[(-2+5^4)x3^6]:3^3:(-7+4)^4+(-3)^3

Answer 1

[tex]a) 2^0+(-3)^2*(-4+6)^5*(8-10)^6-2^{10}*(-1+3)^3= \\ =1+9*2^5*(-2)^6-2^{10}*2^3=1+9*32*64-1024*8= \\ =1+18432-8192=10241 \\ b) [(-2+5^4)*3^6]:3^3:(-7+4)^4+(-3)^3= \\ =[(-2+625)*729]:27:81-27=[623*729]:27:81-27= \\ =454167:27:81-27=180,(6)[/tex]
