Question

2x - 36 = 4⁶ : 4³

5^x+ 11= 36

Answer 1

2x - 36 = 4⁶ : 4³

2x - 36 = 64

2x = 64 + 36 

2x = 100

x = 100 : 2 

x = 50 

5^x+ 11= 36

5^x = 36 - 11 

5^x = 25 

=> x = 2

k mik nha làm ơn 

Answer 2

a)\(2x-36=4^6:4^3\Rightarrow2x-36=4^3\Rightarrow2x-36=64\Rightarrow2x=64+36\Rightarrow2x=100\Rightarrow x=50\)

b)\(5^x+11=36\Rightarrow5^x=36-11\Rightarrow5^x=25\Rightarrow x=2\)

Answer 3

     2x - 36 = 4⁶ : 4³

=> 2x - 36 = 64

=> 2x       = 64+36

=> 2x       = 100

=> x         = 100 : 2

=> x         = 50

     5^x + 11 = 36

=> 5^x         = 36 - 11 

=> 5^x           = 25

=> 5^x         = 5²

=> x          = 2

k mình nha !!!

Answer 4

2x-36=4⁶:4³

=>2x-36=4^6-3

=>2x-36=4³

=>2x-36=64

=>x=64:2

=>x=32

5^x+11=36

=>5^x=36-11

=>5^x=25

Mà : 5^x=25;5²=25

=>5^x=5²=25

=>x=2
