a) 3.3^4.3^5 = 3^10

b) 7^3 : 7^2 : 7 = 7^1

c) (x^4)^3 = x^12

a) `7^4 .7^5 .7^6 = 7^(4+5+6)=7^(15)`

b) `(54:3^7) .324 =( 2.3^3 : 3^7).2^2 x3^4`

`=(2: 3^4).3^4 .2^2`

`= 2.2^2=2^3`

c) `[(8+2^2).10^100] : (10^0 .10^94)`

`=(12 . 10^100) : 10^94`

`=12 . (10^100 : 10^94)`

`=12 . 10^6`

d) `a^9 :a^9 = a^(9-9)=a^0`

Sai nha ban

a) \(7^{15}\)

b)\(162^8\).    2

c)\(10^8\)

d) \(a^0\)

Xin lỗi nha mk hơi vội nên có sai thì bạn châm trc cho mk nha.

a)  6 9 : 6 7 = 6 9 - 7 = 6 2

b)  7 5 : 7 2 = 7 5 - 2 = 7 3

c)  11 8 : 11 3 : 11 2 = 11 8 - 3 - 2 = 11 3

d)  x 8 - 7 - 1 = x 0 = 1

a)  6 2

b)  7 3

c)  11 3

d)  x 0

1) 

g) \(24+5x\text{=}7^5:7^3\)

\(24+5x\text{=}7^{5-3}\)

\(24+5x\text{=}7^2\text{=}49\)

\(5x\text{=}49-24\text{=}25\)

\(x\text{=}5\)

h) \(x:2^2\text{=}2^3\)

\(x\text{=}2^3.2^2\)

\(x\text{=}2^5\text{=}32\)

2) 

a) \(2^{10}.8.2^3\text{=}2^{10}.2^3.2^3\text{=}2^{10+3+3}\text{=}2^{16}\)

\(b)3^5:27\text{=}3^5:3^3\text{=}3^{5-3}\text{=}3^2\)

\(c)5^2.125\text{=}5^2.5^3\text{=}5^{2+3}\text{=}5^5\)

\(d)6^6:36\text{=}6^6:6^2\text{=}6^{6-2}\text{=}6^4\)

1.

g) \(24+5x=7^5:7^3\left(=7^{5-3}\right)\) -> Trong ngoặc ko cần viết nha

\(24+5x=7^2=49\)

\(5x=49-24\)

\(5x=25\)

\(x=25:5\)

\(=>x=5\)

h) \(x:2^2=2^3\)

\(x=2^3.2^2\)

\(=>x=2^5\)

2.

a) \(2^{10}.8.2^3=2^{10}.\left(2^3\right)2^3=2^{10+3+3}=2^{16}\)

b) \(3^5:27=3^5:\left(3^3\right)=3^{5-3}=3^2\)

c) \(5^2.125=5^2.\left(5^3\right)=5^{2+3}=5^5\)

d) \(6^6:36=6^6:\left(6^2\right)=6^{6-2}=6^4\)

Công thức:

\(a^m.a^n=a^{m+n}\)

\(a^m:a^n=a^{m-n}\)

\(#Wendy.Dang\)

\(5^6:5^3=5^{6-3}=5^3\)

\(a^4:a=a^4:a^1=a^{4-1}=a^3\)

a)=5³

b)=a³
