Đáp án:
Giải thích các bước giải:
`a)19.64+36.19`
`=19.(64+36)`
`=19.100`
`=1900`
`b)2^2` `.3-(1^{10}+8)`
`=4.3-(1+8)`
`=12-9`
`=3`
`c)7^2-36:3^2`
`=49-36:9`
`=49-4`
`=45`
`d)150-[10^2.(14-11)^2` .`2007^0`]
`=150-(100.3^2.1)`
`=150-(100.9)`
`=150-900`
`=-750`.
`e)59-[90-(17-8)^2]`
`=59-(90-9^2)`
`=59-(90-81)`
`=59-9`
`=50`.
