Question

25x8³-23x8^{3  ?         tính bằng cách thuận tiện}

 

Answer 1

8^3 nhân (25-23)

8^3 nhân 2

tự tính tiếp nhé em

Answer 2

=2.8³=2.(2³)³=2.2⁹=2¹⁰=1024

Answer 3

\(25.8^3-23.8^3\)

\(=8^3\left(25-23\right)\)

\(=8^3.2\)

\(=\left(2^3\right)^3.2\)

\(=2^9.2\)

\(=2^{10}\)

Answer 4

\(=8^3.\left(25-23\right)\)

\(=8^3.2\)

\(=\left(2^3\right)^3.2\)

\(=2^9.2\)

\(=2^{10}\)

Answer 5

25.8³-23.8³=8³(25-23)

                   =512.2=1024

Answer 6

25.8³-23.8³

=8³(25-23)

=512.2=1024

Answer 7

25.8³-23.8³

=8³(25-23)

=512.2=1024

Answer 8

25.8³-23.8³

=8³(25-23)

=512.2=1024
