Question

[Phương Anh Nguyễn]

a) 3^6.3^7=

b) x^10:x^6:x

c) a^5.a^9

d) 2^3.8^5.16^4

e) 25^3.5^5.3125

f) a^10.a^4:a^12

Answer 1

[Minh Hiếu]

a) \(3^6.3^7\) \(=3^{13}\)

b) \(x^{10}:x^6:x\)

\(=x^{10}:x^7\)\(=x^3\)

c) \(a^5.a^9=a^{14}\)

Answer 2

[Nguyễn Hoàng Minh]

\(a,=3^{6+7}=3^{13}\\ b,=x^{10-6-1}=x^3\\ c,=a^{5+9}=a^{14}\\ d,=2^3\cdot2^{15}\cdot2^{16}=2^{34}\\ e,=5^6\cdot5^5\cdot5^5=5^{16}\\ f,=a^{10+4-12}=a^2\)
