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
b)(0,25)4.1024=\(\frac{1}{4}\)4.1024=\(\frac{1}{256}\).1024=4
a, ( 0,125 )3 . 512
=( \(\frac{1}{8}\))3 . 512
= \(\frac{1}{512}\) . 512
= 1
b, ( 0,25) 4 . 1024
= \(\left(\frac{1}{4}\right)\)4 . 210
= \(\frac{1}{\left(2^2\right)^4}\). 210
= \(\frac{1}{2^8}\). 210
= 22
= 4
