Đáp án+Giải thích các bước giải:
a,
`\frac{4^2 .4^3}{2^{10}}`
`=\frac{2^{10}}{2^{10}}`
`=1`
b,
`\frac{(0,6)^5}{(0,2)^6}`
`=\frac{(0,2)^5 .(0,3)^5}{(0,2)^6}`
`=\frac{0,3^5}{0,2}`
`=1215`
c,
`\frac{2^7 .9^3}{6^5 .8^2}`
`=\frac{2^7 .3^6}{2^5 .3^5 .2^6}`
`=\frac{3}{2^4}`
`=\frac{3}{16}`
d,
`\frac{6^3+3.6^2+3^3}{-13}`
`=\frac{3^3(2^3+2^2+1)}{-13}`
`=\frac{3^3 .13}{-13}`
`=-3^3`
`=-27`
