Question

①(0.25^2008)*(4^2009)-(8^100)*0.5^300得多少 ②(0.125^3)*(0.25^3)

Answer 1

①(0.25^2008)*(4^2009)-(8^100)*0.5^300

=(0.25^2008)*(4^2008)*4-(2^300)*0.5^300

=(0.25*4)^2008*4-(2*0.5)^300

=1^2008 *4- 1^300

=4-1

=3

②(0.125^3)*(0.25^3)*(2^6)*2^12

=(0.125^3)*(0.25^3)*(4^3)*8^4

=(0.125^3)*(0.25^3)*(4^3)*8^3*8

=(0.125×8)^3*(0.25*4)^3*8

=1*1*8

=8
