Question

Giải chi tiết

Answer 1

a: =>x+1=5

=>x=4

b: =>2^x=1024/256=4

=>x=2

c: \(\Leftrightarrow4^x\cdot4^3=4^{16}\)

=>x+3=16

=>x=13

d: \(\Leftrightarrow2^x=2^4\)

hay x=4

Answer 2

`a, => 3^(x+1) = 3^5`

`=> x + 1 = 5`

`=> x = 4`

`b, <=> 2^x xx 2^8 = 2^10`

`=> 2^(x+8) = 2^10`

`=> x = 2`

`c, <=> 4^(3+x) = 4^16`

`=> x = 13`

`d, 2^x = 2^4`

`<=> x = 4`
