câu A nha bạn

đáp án A.63 nha bạn

10 tháng 8 2016

Gọi số cần tìm là a lập biểu thức :

a . 3,5 : 4 = 6,3

=> a.3,5 = 6,3 . 4

=> a.3,5 = 25,2

=> a = 25,2 : 3,5

=> a = 7,2

10 tháng 8 2016

    a.3,5:4=6,3
=> a.3,5= 6,3.4
=> a.3,5= 25,2
=> a= 25,2: 3,5
=> a=7,2

a) \(3^6.3^7\) \(=3^{13}\)

b) \(x^{10}:x^6:x\)

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

c) \(a^5.a^9=a^{14}\)

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

\(=3,6\times\left(63+36+1\right)\)

\(=3,6\times100\)

\(=360\)

 Câu 2 :\(3,5\times20,2+6,5\times27,9+3,5\times2,2-6,5\times5,5\)

\(=3,5\times\left(20,2+2,2\right)+6,5\times\left(27,9-5,5\right)\)

\(=3,5\times22,4+6,5\times22,4\)

\(=22,4\times\left(3,5+6,5\right)\)

\(=22,4\times10\)

\(=224\)
