Bài 1:
a) \(\left(0,125\right)^3.512\)
\(=\left(0,125\right)^3.8^3\)
\(=1^3\)
\(=1.\)
b) \(\left(0,25\right)^4.1024\)
\(=\left[\left(0,25\right)^2\right]^2.32^2\)
\(=\left(0,0625\right)^2.32^2\)
\(=2^2\)
\(=4.\)
Chúc bạn học tốt!
a) (0,125)3.512=\(\frac{1}{8}\)3.512=\(\frac{1}{512}\).512=1

= \(\frac{1}{\left(2^2\right)^4}\). 210
= \(\frac{1}{2^8}\). 210
= 22
= 4
