a) \(\left(\frac{1}{16}\right)^{25}\div\left(\frac{1}{2}\right)^{30}=\left(\frac{1}{2^4}\right)^{25}\div\left(\frac{1}{2}\right)^{30}=\left[\left(\frac{1}{2}\right)^4\right]^{25}\div\left(\frac{1}{2}\right)^{30}=\left(\frac{1}{2}\right)^{4.25}\div\left(\frac{1}{2}\right)^{30}\)

\(=\left(\frac{1}{2}\right)^{100}\div\left(\frac{1}{2}\right)^{30}=\left(\frac{1}{2}\right)^{100-30}=\left(\frac{1}{2}\right)^{70}\)

b) \(584^{100}\div292^{100}=\left(584-292\right)^{100}=292^{100}\)

c) \(125^4\cdot16^3=\left(5^3\right)^4\cdot\left(2^4\right)^3=5^{3\cdot4}\cdot2^{4\cdot3}=5^{12}\cdot2^{12}=\left(5+2\right)^{12}=7^{12}\)

\(y-125:5=316\times6\)

\(y-625=1896\)

\(y=1896+625\)

\(y=2521\)

y-125:5 = 136*6

\(y-125:5=316\times6\)

\(y-625=1896\)

\(y=1896+625\)

\(y=2521\)

y - 125 : 5 = 316 x 6 

y - 25 = 1896

y = 1896 + 25 

y = 1921

125 + 125 + 125 + 125 - 25 - 25 - 25 - 25

= ( 125 - 25 ) + ( 125 - 25 ) + ( 125 - 25 ) + ( 125 - 25 )

= 100 + 100 + 100 + 100

= 100 x 4 

= 400

= 400 nhé!
