A=4

 câu C mh ko biết, xin lỗi nha

0,25⁴ . 1024

= (\(\frac{1}{4}\))⁴ . 1024

= \(\frac{1}{256}\) . 1024

= 4

Chúc bạn học tốt!

\(\left(0,25\right)^4.1024=\left(\frac{1}{4}\right)^4.1024=\frac{1}{256}.1024=4\)

Chức bạn học tốt !

=1/256 X 1024=4 K MK NHA

\(0,25^4.1024\\ =\left(\dfrac{1}{4}\right)^4.1024\\ =\dfrac{1}{256}.1024\\ =4\)

\(\left(0,25\right)^4.1024\)

\(=\left(\frac{1}{4}\right)^4.32^2\)

\(=\left[\left(\frac{1}{4}\right)^2\right]^2.32^2\)

\(=\left(\frac{1}{16}\right)^2.32^2\)

\(=\left(\frac{1}{16}.32\right)^2\)

\(=2^2\)

\(=4.\)

Chúc bạn học tốt!

Ta có: \(\left(0,25\right)^4.1024\)

\(=\left(\frac{1}{4}\right)^4.32^2\)

\(=\left[\left(\frac{1}{4}\right)^2\right]^2.32^2\)

\(=\left(\frac{1}{16}\right)^2.32^2\)

\(=\left(\frac{1}{16}.32\right)^2\)

\(=2^2\)

\(=4\)

Chúc bạn hok tốt!!! Đặng Quốc Huy

Ta có: (0,25)⁴.1024

= [(0,25)² ]² .32²

=(\(\frac{1}{6}\))² .32²

⁼(\(\frac{1}{6}\).32)²

=(\(\frac{32}{6}\))²

=2²

=4

Vậy (0,25)² .1024=4

a) \(\left(\dfrac{1}{5}\right)^5.5^5=1\)

b) \(\left(0,125\right)^3.512=1\)

c) \(\left(0,25\right)^4.1024=4\)

a) (1/5)^5 . 5^5 = (1/5. 5)^5 = 1^5= 1

b) (0,125)^3. 512= (0,125)^3 . 8^3 = (0,125. 8)^3 = 1^3= 1

c) (0,25)^4. 1024= [(0,25)^2]^2. 32^2= (1/6)^2. 32^2=(1/6.32)^2= (32/6)^2 =2^2= 4

a, \(\left(\dfrac{1}{5}\right)^5.5^5\) =0,00032. 3125= 1

b, \(\left(0,125\right)^3.512\)= 0.001953125. 512=1

c, \(\left(0,25\right)^4.1024\) =0,00390625.1024=4

a/ \(\left(\dfrac{1}{5}\right)^5.5^5=\left(\dfrac{1}{5}.5\right)^5=1^5=1\)

b/ \(\left(0,125\right)^3.512=\left(0,125\right).8^3=\left(0,125.8\right)^3=1^3=1\)

c/ \(\left(0,25\right)^4.1024=\left(0,25^2\right)^2.32^2=\left(\dfrac{1}{6}\right)^2.32^2=\left(\dfrac{1}{6}.32\right)^2=16^2\)

\(a,\left(\dfrac{1}{5}\right)^5.5^5=\left(\dfrac{1}{5}.5\right)^5=1^5=1\)

\(b,\left(0,125\right)^3.512=\left(0,125\right)^3.8^3=\left(0,125.8\right)^3=1^3=1\)

\(c,\left(0,25\right)^4.1024=\left(0,25\right)^4.4^4.4=\left(0,25.4\right)^4.4=1^4.4=1.4=4\)
