2:

a: n=5^4

=>n=625

b: n^3=125

=>n^3=5^3

=>n=5

c: 11^n=1331

=>11^n=11^3

=>n=3

\(a,5\cdot p\cdot5\cdot p\cdot2q\cdot4q\)

\(=5^2\cdot p^2\cdot2\cdot q\cdot2^2\cdot q\)

\(=5^2\cdot2^3\cdot p^2\cdot q^2\)

\(b,a\cdot a+b\cdot b+c\cdot c\cdot c+d\cdot d\cdot d\cdot d\)

\(=a^2+b^2+c^3+d^4\)

Câu 1:

a)\(2^3.2^2.2^4=2^{\left(3+2+4\right)}=2^9\)

b)\(10^2.10^3.10^5=10^{\left(2+3+5\right)}=10^{10}\)

c)\(x.x^5=x^6\)

d)\(a^3.a^2.a^5=a^{\left(2+3+5\right)}=a^{10}\)

cái phép x ý tại sao lại ra X⁶

tại sao lại ra như thế trả lời đi

a) \(2^3.2^2.2^4=2^{3+2+4}=2^9\)

b) \(10^2.10^3.10^5=10^{2+3+5}=10^{10}\)

c) \(x.x^5=x^{1+5}=x^6\)

d) \(a^3.a^2.a^5=a^{3+2+5}=a^{10}\)

`3.5 .15.15  = 3.5.3.5.3.5 = 3^3.5^3`

`2.2.5.2.5 = 2^3 . 5^2`

`1000.10 .10 = 10^3 .10^1 . 10^1 = 10^5`

`a.a.a.b.b.b = a^3 . b^3`

`n.n.n + p.p = n^3 . p^2`

a: =15*15*15=15^3

b: =2^3*5^2

c: =10^3*10^2=10^5

d: =a^3*b^3

e: =n^3+p^2

A. \(256:2^5\cdot4\)

\(=2^6:2^5\cdot2^2\)

\(=2^{6-5+2}\)

\(=2^3\)

B. \(\left(4x^2\right)^8:\left(4x^2\right)^4:\left(4x^2\right)^2\)

\(=\left(4x^2\right)^{8-4-2}\)

\(=\left(4x^2\right)^2\)

\(=\left[\left(2x\right)^2\right]^2\)

\(=\left(2x\right)^4\)

C. \(y^{50}:\left(y^5\right)^3:\left(y^2\right)^{10}\)

\(=y^{50}:y^{15}:y^{20}\)

\(=y^{50-15-20}\)

\(=y^{15}\)

243 : 3³ : 3 = 3⁵ : 3³ : 3¹ = 3^{5 - 3 - 1} = 3¹

a, 243 : 3³ : 3= 3⁵ : 3³ : 3 = 3^5-3-1 = 3

hoctot

\(=\left(-2\right)^6.5^3\)

a)(-8).(-2)^3.125=(-2)^3.(-2)^3.5^3=1^3=1

lm hộ mik câu này luôn nha
