Question

B1: Tính

a, \(\left(-3\right)^2.\left(-3\right)^3\)

b, \(\left(-5\right)^5:\left(-5\right)^5\)

c, \(\left(\dfrac{1}{4}\right)^4.2^8\)

d, \(\left(\dfrac{1}{9}\right)^5.3^{11}\)

B2: Viết 125; 3125 dưới dạng lũy thừa

Answer 1

`a, = -3^5 = -243`

`b, = 1`

`c, = (1/2)^8 . 2^8 = 1`

`d, = (1/3)^10 . 3^11 = 3`

`B2: 125 = 5^3`

`3125 = 5^5`.
