Question

15 upon 4 to the power 3 / 5 upon 4 ^ 3 = 3x in this question find the value of x

Answer 1

Given equation is $\frac{\frac{15}{4^3}}{\frac{5}{4^3}}=3x$

Apply formula (a/b) / (c/d) = (a/b) * (d/c)

We get:

$\frac{15}{4^3}*\frac{4^3}{5}=3x$

4^3 gets cancelled

$\frac{15}{5}=3x$

3=3x

divide both side by 3

we get 1=x

Hence final answer is x=1.
