Question

thu gọn:
7^3.7^5
3^7.3^9
(-6)^5.(-6)
(-2)^5.(-2)^6
(-0,1)^2.(-0,1)^3
(4/5)^4.(4/5)^3
(1/2).(1/2)^2
(-1/2).(-1/2)^3
(-3/2)^3.(-3/2)^2
(-2).2^8

Answer 1

a: \(=7^8\)

b: \(=3^{16}\)

c: \(=\left(-6\right)^6=6^6\)

d: \(=\left(-2\right)^{11}\)

e: \(=\left(-0.1\right)^5\)

f: \(=\left(\dfrac{4}{5}\right)^7\)

Answer 2

`7^3*7^5=7^{3+5}=7^8`

`3^7*3^9=3^{7+9}=3^16`

`(-6)^5*(-6)=(-6)^6`

`(-2)^5*(-2)^6=(-2)^{5+6}=(-2)^{11}`

`(-0,1)^2*(-0,1)^3=(-0,1)^{2+3}=(-0,1)^6`

Answer 3

7^3.7^5 = 7^8

3^7.3^9 = 3^16

(-6)^5.(-6) = (-6)^6

(-2)^5.(-2)^6 = (-2)^11

(-0,1)^2.(-0,1)^3 = (-0,1)^5

(4/5)^4.(4/5)^3 = (4/5)^7

(1/2).(1/2)^2 = (1/2)^3

(-1/2).(-1/2)^3 = (-1/2)^4

(-3/2)^3.(-3/2)^2 = (-3/2)^5

(-2).2^8 ( câu này thì tui ko nhớ, sorry )
