Question

Viết các số dưới đây dưới dạng lũy thừa

2.4.16.32.2 mũ 4

(4.2 mũ 5) : (2³. 1/16)

9.3³ . 1 phần 81 .27

2 mũ 2 .4.32/2 mũ 2 . 2 mũ 5

Answer 1

a) \(2.4.16.32.2^4=2.2^2.2^4.2^5.2^4=2^{16}\)

b) \(\left(4.2^5\right):\left(2^3.\frac{1}{16}\right)=\left(2^2.2^5\right):\left(2^3.\left(\frac{1}{2}\right)^4\right)=2^7:\frac{1}{2}=2^8\)

c) \(9.3^3.\frac{1}{81}.27=3^2.3^3.\left(\frac{1}{3}\right)^4.3^3=3^4\)

d)\(2^2.4.\frac{32}{2^2}.2^5=2^2.2^2.2^3.2^5=2^{12}\)
