Bài 1:

a, 60...0 (21 chữ số 0)

= 6.10²¹

b, 50...0 (15 chữ số 0)

 = 5.10¹⁵

2, Viết các số sau dưới dạng lũy thừa của 10

a, 10000...0 (100 chữ số 0 )

  = 10¹⁰⁰

b,  1000...0(n chữ số 0)

= 10ⁿ

a)8⁸

b)2³.3²

c)10⁶

k mik nha

a,8^8

b,2^3.3^2

c, 10.100.1000=1000.1000=1000^2

A

\(5^1.5^3.5^4\)=\(5^{1+3+4}=5^8\)

B

\(10^1.10^2.10^3=10^{1+2+3}=10^6\)

C

\(8^4.16^5.32^1\)

d

\(27^4.81^{10}\)
