25. 5. 125 = 5⁶

a.2.8.16=2^1.2^3.2^4=2^8

b.25.5.125=5^2.5^1.5^3=5^6

1. a. 2.8.16=16.16=\(16^2\)

    b. 25.5.125=125.125=\(125^2\)

    c. \(\frac{2}{3}.\frac{4}{9}.\frac{8}{27}=\frac{8}{27}.\frac{8}{27}=\left(\frac{8}{27}\right)^2\)

k cho em nha, em nhớ là em bày chị rồi mà

c.2^6/3^6

ta có :

\(3^3.7^3=\left(3.7\right)^3=21^3\)

3³7³=(3.7)³

49.7.343 = 7 2 .7.7 3 = 7 6

3.27.9 = 3.3 3 .3 2 = 3 6

3.27.9 = 3⁶

2 3 . 8 27 . 16 81 = 2.2 3 .2 4 3.3 3 .3 4 = 2 8 3 8 = 2 3 8

2 3 . 4 9 . 8 27 = 2 3 6

3 4 . 9 16 . 27 64 = 3.3 3 .3 3 4.4 2 .4 3 = 3 4 6
