Question

若2乘以8的n次方乘以16的n次方=2的22次方,则n的值是多少

还要解释，过程喏，先谢啦

Answer 1

2乘以8的n次方乘以16的n次方=2的22次方

2*8^n*16^n=2^22
2*(2^3)^n*(2^4)^n=2^22
2*2^(3n)*2^(4n)=2^22
2^(1+3n+4n)=2^22
则
1+3n+4n=22
7n=21
n=3

Answer 2

2乘以8的n次方乘以16的n次方=2的22次方
2*8^n*16^n=2^22
2*(2^3)^n*(2^4)^n=2^22
2*2^(3n)*2^(4n)=2^22
2^(1+3n+4n)=2^22
则
1+3n+4n=22
7n=21
n=3

Answer 3

2乘以8的n次方乘以16的n次方=2的22次方
2*8^n*16^n=2^22
2*(2^3)^n*(2^4)^n=2^22
2*2^(3n)*2^(4n)=2^22
2^(1+3n+4n)=2^22
则
1+3n+4n=22
7n=21
n=3

Answer 4

2乘以8的n次方乘以16的n次方=2的22次方n=3

Answer 5

2*8^n*16^n=2^22
2*(2^3)^n*(2^4)^n=2^22
2*2^(3n)*2^(4n)=2^22
2^(1+3n+4n)=2^22
则
1+3n+4n=22
7n=21
n=3
