规定运算:“△”,“※”,使得a△b=ab-1,a※b=a/b+1求(6△8)※[6※(-8)]的值.急++++++++++++++++++++++++++++++++++++++++++++++++++++
(6△8)※[6※(-8)]
=(6*8-1)※[6/(-8)+1]
=47※(1/4)
=47/4+1
=51/4

6※(-8)=1/4
6△8=49
(6△8)※[6※(-8)]=49*4+1=197

规定运算符号△※使得a△b=ab-1,a※b=a/b+1,求(6※8)※【6※(-8)】的值 规定运算:“△”,“※”,使得a△b=ab-1,a※b=a/b+1求(6△8)※[6※(-8)]的值.急++++++++++++++++++++++++++++++++++++++++++++++++++++ “△”表示一种运算符号,规定A△B=A×B-(A+B),求8△6. 规定一种新运算;a△b=a*b-a-b+1,则(-3)△4=快 规定一种新的运算:a△b=a*b-a-b+1,计算(-5)△6= 现规定一种新运算a※,b=ab+a-b,则1※(-2)=____________还有一个:现规定一种新的运算“*”,使得a*b=b^a,则3*(-2)等于_______A.5 B.-6 C.-8 D.9 1.规定一种新的运算☆,使得a☆b=ab+a+b .若2☆x=-5,求x的值 现规定一种运算a△b=ab+a-b,其中啊a,b为有理数,则a△b+(b-a)△b等于? 现规定一种运算:a△b=ab+a-b,其中a,b为实数,则a△b+(b-a)△b的值等于多少 限规定一种运算:a※b=ab+a-b,则a※b+(b-a)※b=【】 现规定运算a※b=(a+2)x2-b,则5※(-4) “△”是一种新运算,规定:a△b = 3a + 2b,那么2△3 =_______________. 规定运算△:a△b=5a-2b,那么3△4的得数是多少 规定一种运算:当a>b时,a*b=a*b/a+b;当a 请你规定一种适合任意非零实数a,b的新运算“a⊕b”,使得下列算式成立:1⊕2=2⊕1=3,(-3)⊕(-4)=(请你规定一种适合任意非零实数a,b的新运算“a♁b”,使得下列算式成立:1♁2=2♁1=3, 现规定一种运算:a*b=ab+a-b,则(b-a)*(a+b)= 规定一种运算:a*b=ab+a+b,则(-a)*(-b)+a*b的结果是 规定a*b=3a-2b,则a*b*b=?*为运算符号
