lm hộ mik câu này luôn nha

27.(-2)³.(+343)

a. 8². 32⁴ = 2⁶. 2²⁰ = 2²⁶

b. 27³. 9⁴. 243 = 3⁹. 3⁸. 3⁵ = 3²²

c. 5 .125 . 625 = 5 . 5³. 5⁴ = 5⁸

d.10 . 100 . 1000 = 10 . 10². 10³ = 10⁶

e. 8⁴. 16⁵. 32 = 2¹². 2²⁰. 2⁵ = 2³⁷

f. 27⁴ . 81¹⁰ = 3¹². 3⁴⁰ = 3⁵²

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

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

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

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

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

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