Question

Rút gọn biểu thức sau:

A= 4².25²+32.125/2³.5²

Answer 1

\(A=4^2.25^2+\dfrac{32.125}{2^3}.5^2\)

\(A=16.125+8.125.25\)

\(A=16.125+200.125\)

\(A=\left(16+200\right).125\)

\(A=216.125=27000\)

Answer 2

\(\dfrac{4^2.25^2+32.125}{2^3.5^2}\) =\(\dfrac{\left(2^2\right)^2.\left(5^2\right)^2+2^5.5^3}{2^3.5^2}=\dfrac{2^4.5^4+2^5.5^3}{2^3.5^2}=\dfrac{2^9+5^7}{2^3.5^2}\)

= 2⁶ + 5⁵

nếu biểu thức trên là p/s như mk lm thì hãy tick nha
