Question

if power of 2 3x-1+10 \7=6 then x=?​

Answer 1

Answer:

(2^3x-1 +10)÷7=6

(2^3x-1 +10)/7=6

(2^3x-1 +10)=42

2^3x-1=42–10=32

(2)^3x-1=(2)^5

3x-1=5

3x=6

x=6/3

x=2 , Answer

Step-by-step explanation:

Answer 2

The value of x is 2

Step-by-step explanation:

It has been given that

$\frac{2^{3x-1}+10}{7}=6$

Cross multiplying, we get

$2^{3x-1}+10=42$

Subtract 10 to both sides

$2^{3x-1}=32$

Write 32 in exponent form

$2^{3x-1}=2^5$

Since, base of both sides of the equation is 2. Hence, the exponent must be equal.

$3x-1 = 5$

Solve for x

$3x=6\\\\x=2$
