✔ 最佳答案
(-8)^4+7^2*(-2^6)= 8x8x8x8 + 7x7x(-2)x(-2)x(-2)x(-2)x(-2)x(-2)
= 64x64 +49x(64)
= 64x(64+49)
= 64x113)
=7232

Corrections:(-8)^4+7^2*(-2^6)= 8x8x8x8 + 7x7x(-2x-2x-2x-2x-2x-2)= 64x64 - 49x(64)= 64x(64-49)= 64x15=960

(-8)^4+7^2*(-2^6)= 8x8x8x8 + 7x7x(-2x2x2x2x2x2)= 64x64 - 49x(64)= 64x(64-49)= 64x15=960

=(-8)*(-8)*(-8)*(-8)+7*7*-(2*2*2*2*2*2)
=4096+49*-(64)
=4096+49*-64
=4096+-3136
=4096-3136
=960
=4096+49*-(64)
=4096+49*-64
=4096+-3136
=4096-3136
=960

(-8)^4+7^2x(-2^6)
=(-8x)(-8x)(-8x)(-8x)+[(7x7)(-2x-2x-2x-2x-2x-2)]
=4096+[49x64]
=4096+3136
=7232
**我都係中1架~~呢個式岩架喇...我做完好耐~

唔該你寫個式寫好d喇...邊個出架!!!(-2^6)唔同-(2^6)架!!(-8)^4+7^2x-(2^6)=(-8x)(-8x)(-8x)(-8x)+(7^2x-(2x2x2x2x2x2)=4096+49x-64=4096-3136=960
=(-8x)(-8x)(-8x)(-8x)+[(7x7)(-2x-2x-2x-2x-2x-2)]
=4096+[49x64]
=4096+3136
=7232

本來(-8)^4+7^2*(-2^6)
=(-8)*(-8)*(-8)*(-8)+7*7*(-2)*(-2)*(-2)*(-2)*(-2)*(-2)
=64*64+49*4*4*4
=64*64+49*64
=(64+49)64
=7232
但你講:
hckckn已經錯了...
你要記住我既^6係系2既後面, 而非整個-2的後面喔..

咁條式應該係:
(-8)^4+7^2*(-[2^6])
=(-8)*(-8)*(-8)*(-8)+7*7*-(2*2*2*2*2*2)
=4096+49*-(64)
=4096+(-3136)
=4096-3136
=960
條式係點嫁呢?比左兩個ANS你,你自己睇式然後簡啦!
=(-8)*(-8)*(-8)*(-8)+7*7*(-2)*(-2)*(-2)*(-2)*(-2)*(-2)
=64*64+49*4*4*4
=64*64+49*64
=(64+49)64
=7232

(-8)^4+7^2*(-2^6)
= -8x-8x-8x-8 + 7x7x-{(2)x(2)x(2)x(2)x(2)x(2)}
= 64x64 +49x(-64)
= 64x64-3136
=960

kellylam824, 咁就奇la, hckckn係16:28:43做左個錯既答案, 但係於16:36就改番個正確答案, 佢個正確擺明係遲過我la, 我係16:35:01就已經俾左個正確既答案俾人la woo, 咁點解hckckn會係最佳答案ar????我(心如止水)起碼一早就計到360俾你la....其他人都計錯點解我唔係最佳答案ar???
= -8x-8x-8x-8 + 7x7x-{(2)x(2)x(2)x(2)x(2)x(2)}
= 64x64 +49x(-64)
= 64x64-3136
