Question

4^2x-1 -16^x-1 =384​

Answer 1

Step-by-step explanation:

384=1/3x^8^2x^6

Two solutions were found :

x = ± 70th root of 1152 = ± 1.1059

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x6" was replaced by "x^6". 1 more similar replacement(s).

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

384-(1/3*x^8^2*x^6)=0

Step by step solution :

Step 1 :

1.1 8 = 23

(8)2 = (23)2 = 26

Equation at the end of step 1 :

1

384 - ((— • (x2^6)) • x6) = 0

3

Step 2 :

1

Simplify —

3

Equation at the end of step 2 :

1

384 - ((— • x64) • x6) = 0

3

Step 3 :

Equation at the end of step 3 :

x64

384 - (——— • x6) = 0

3

Step 4 :

Multiplying exponential expressions :

4.1 x64 multiplied by x6 = x(64 + 6) = x70

Equation at the end of step 4 :

x70

384 - ——— = 0

3

Step 5 :

Rewriting the whole as an Equivalent Fraction :

5.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 3 as the denominator :

384 384 • 3

384 = ——— = ———————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
