Question

1) 2^x=0,5
2)5^4x+1=625
уравнения

Answer 1

2^4х =0.5
2^4x=1/2
2^4x=2^-1
4x= - 1
x= -1/4
2^(4*(-1/4))=0.5
2^-1=0.5
1/2=1/2

5^(4x+1)=625
5^(4x+1)=5^4
4x+1=4
4x=4-1
4x=3
x=3/4
5^(4 *3/4 +1)=5^4
5^4=5^4

Answer 2

В первом не 2^4х ( а 2^х )

Answer 3

2^х=0,5

Answer 4

2^х=2^-1

Answer 5

х= - 1

Answer 6

N 1
2 ^ X = 0,5
2 ^ X = 2 ^ - 1
X = - 1
Ответ ( - 1 )
N 2
5 ^ 4x + 1 = 625
5 ^ 4x + 1 = 5 ^ 4
4x + 1 = 4
4x = 3
X = 0,75
Ответ 0,75 ( или 3/4 )
