Question

BÀI 4 : RÚT GỌN

\(B=\frac{\left(5^4\right)-\left(5^3\right)}{125}\)

Answer 1

Rễ thui ta có: \(B=\frac{\left(5^4\right)-\left(5^3\right)}{125}=\frac{500}{125}=4\)

Answer 2

5⁴ = 5*5*5*5= 625 

5³=5*5*5=125 

5^{4 -} 5³ = 625 - 125 = 500 

Vậy B = 500/ 125 

vậy B = 4 

Answer 3

Ta tính bình thường nha

\(=\frac{\left(5^4\right)-\left(5^3\right)}{125}=\frac{625-125}{125}=\frac{500}{125}=4\)

Vậy \(\frac{\left(5^4\right)-\left(5^3\right)}{125}=4\)

Answer 4

B = \(\frac{\left(5^4\right)-\left(5^3\right)}{125}=\frac{625-125}{125}=\frac{500}{125}=4\) 4

Answer 5

Đơn giản Hóa : \(B=\frac{\left(5^4\right)-\left(5^3\right)}{125}=\frac{500}{125}=\frac{4}{1}\)
