还用英文的,这年头~
1、解方程：(2p)2/3 + 12 = 76,即(2p)2/3 = 64,即(2p) = 32 * 3,p = 48.
2、解方程：13^-a = 1/169,即13^a = 169,a = 2.
3、还是解方程,写好一点才好看哦.大概是3^（1-2x） = 243,对吧?243 / 3 = 81 = 9^2 = 3^4,即3^（1-2x）= 3^5,即1-2x = 5,x = 2.
4、都是解方程,但这个不是方程,不懂!
5、又是解方程2^2t+1-4^t+2^2t-1 =24,即2^2t+1-2^2t+2^2t-1 =24,这到底是写的什么呢?我猜是
2^（2t+1）-2^2t+2^（2t-1） =24,令x = 2^2t,化成2x - x + x / 2 = 24,3x = 48,x = 16,则t = 4.
6、最后一个方程：(9^-1/2 g^3)除(2^-1 g^2) =2/3看不懂,括号里面都两个数之间都没连接符,我猜你还不会用到矩阵运算,打错了吧.
为了抽奖我容易嘛

B

考察主谓一致。句意：不但是他，而且我也能解决这类问题。当句子中又连词连接两个主语时，谓语动词与最近的主语保持一致，离谓语最近的主语为I，故选B。

选C
on the top 主要指在某物的顶端,较具体
eg：on the top of the moutain 在山顶
The dictionary is on the top shelf.
那字典在架子的顶层.
at the top 在某一事物内部的顶端,如在某一网页的顶端,某一纸张的顶端.较抽象
eg：The process begins at the top.
这个过程自上而下开始.
Who is at the top?
谁是最高层?

晓初晴天 共回答了19个问题 | 采纳率89.5%

however=no matter how, whatever = no matter what
所以however whatever的区别,就是how what的区别.
两者都是常用的疑问词,不过how是一个疑问副词,可以理解为一个程度副词,往往是对于一个形容词的程度进行提问时使用的.而what是一个疑问代词,他只能对事物进行提问.
所以,how difficult是在提问“多么困难”,而what difficult是没有意义的.

你的意思就是从句you told me to solve the maths problem作way的同位语,所以只能用that,但一般接同位语的单词都是fact,news,idea,truth,hope,problem,information,wish,promise,answer,evidence,report,explanation,suggestion,conclusion等抽象名词,说明该名词的具体内容.way后面不经常接同位语从句,而且这里用限定比较合适,用说明具体内容不大合理.
如果按你的理解,the way that后面就应该跟解数学题的具体方法,比如换元法啦,叠代法啦等等.

设4^x为t,16^x=（4^x）²=t²,则
∴原式=t²+t-20=0
∴因式分解可得：
（t+5）（t-4）=0
∴t=4或t=-5
∵t=4^x＞0
∴t=4
∴4^x=4
∴x=1
