a) 100 mũ 1
b) 5 mũ 2
c)100 mũ 1
Mình ko bk nên mk dùng là 100 mũ 1 nhé!

a. \(12^2.3^2.2^3=2^4.3^2.3^2.2^3=2^7.3^4\)
b. \(8^3.3^2.6^3=2^9.3^2.2^3.3^3=2^{12}.3^5\)
c. \(5^{32}.5^2=5^{34}\)
d. \(100^6.2^3=\left(2^2.5^2\right)^6.2^3=2^8.5^8.2^3=2^{11}.5^8\)
e. \(100^2:10^2:5^2=\left(10.5.2\right)^2:10^2:5^2=2^2\)
f. \(121^3-11^2=11^6-11^2=11^2\left(11^4-1\right)\)

a) \(2^5:8^4=2^5:\left(2^3\right)^4=2^5:2^{12}=2^{-7}=\frac{1}{2^7}\)\(=\left(\frac{1}{2}\right)^7\)
b) \(25^6:125^3=\left(5^2\right)^6:\left(5^3\right)^3=5^{12}:5^9=5^3\)
c) \(625^2:25^7=\left(5^4\right)^2:\left(5^2\right)^7=5^8:5^{14}=5^{-6}=\frac{1}{5^6}=\left(\frac{1}{5}\right)^6\)
d) \(12^3.3^3=\left(12.3\right)^3=36^3\)
e) \(32^2:2^4=\left(2^5\right)^2:2^4=2^{10}:2^4=2^6\)
g) \(64.2:2^5=2^6.2:2^5=2^7:2^5=2^2\)
Mk làm hộ bn rùi đó nhớ ủng hộ mk nha ^_^
a) (1 phần 2 ) mũ 7
b) 5 mũ 3
c) (1 phần 5 ) mũ 6
d) 36 mũ 3
e) 2 mũ 6
g) 2 mũ 2

A, 2^5 x 8^4 = 2^5 x (2^3)^4 B,25^6 x 125^3=(5^2)^6 x (5^3)^3
= 2^5 x 2^12 =5^12 x 5^9
=2^17 =5^21
Ta có: \(1^3+2^3+3^3+...+n^3=\left(1+2+3+...+n\right)^2\)
a, \(1^3+2^3+3^3+4^3=\left(1+2+3+4\right)^2=10^2\)
b, \(1^3+2^3+3^3+4^3+5^3=\left(1+2+3+4+5\right)^2=15^2\)
c,
\(3^6:3^2+2^3\cdot2^2-2\\ =3^{6-2}+2^{3+2-1}\\ =3^4+2^4\)
\(a,1^3+2^3+3^3+4^3.\)
\(=\left(1+2+3+4\right)^2.\)
\(=10^2=100.\)
\(b,1^3+2^3+3^3+4^3+5^3.\)
\(=\left(1+2+3+4+5\right)^2.\)
\(=15^2=225.\)
(2 phần a, b thì áp dụng công thức: \(1^3+2^3+3^3+...+n^3=\left(1+2+3+...+n\right)^2.\))
