3^2m×9^2等于几3^2m×9^2等于几3^2m×9^2等于几=(3^2)^m*9^2=9^m*9^2=9^(m+2)9^8M3^(2m)×9^2=(3^2)^m×9^2=9^m×9^2=9^(2

3^2m×9^2等于几
3^2m×9^2等于几

3^2m×9^2等于几
=(3^2)^m*9^2
=9^m*9^2
=9^(m+2)

9^8M

3^(2m)×9^2=(3^2)^m×9^2=9^m×9^2=9^(2+m)

3^2m×9^2等于几 M的平方减3等于1,2M减1小于0,M等于几 3×m×m等于几3×m×m等于几3×m×m等于几3×m×m等于几 n-m等于-3则4-2m+2n等于几若|m-3|+|n+2|等于0,则m+2n等于几 12-2（m+3）等于几,要过程! m/3和2m-7/3互为相反数,m等于几（m/3）+1和2m-7/3互为相反数,m等于几若3的m次方等于2,9的n次方等于5,则3的2m减4n加1次方等于几, x的m次方乘x的2m次方等于2,则x的9m次方等于几? 若m根号2减3减5m加3根号2等于有理数,且m等于几? 2+9等于几若-(m+2)=0,则m等于几㎡+2m-1＝0 求m等于几若m的绝对值等于7,则m等于几;若n^2等于36n等于几 24分之18等于72分之几还等于几分之9等于4分之几 84分之28等于12分之几等于几分之2等于3分之几还有啊6除以7等于14分之几等于几分之2436分之24等于12除以几等于几除以9等于几分之二?我这是作业（6m平方+4m-3）-（2m的平方-4m-1）等于几 m的平方减2m等于一,求m等于几?
