Question

What is equivalent to this equation 4^x+3=64

Answer 1

Answer: $2^{(2x+6)}=2^6$

Step-by-step explanation: We are given an exponential equation

$4^{x+3}=64$.

We need to convert it into it's equivalent equation.

Let us factor 4.

4 = 2 × 2

Therefore, 2 × 2 could be written as $(2)^2$.

Now, let us factor 64 in terms of 2's.

64 = 2 × 2× 2× 2× 2× 2 = $2^6$.

Replacing 4 by $2^2$ and 64 by $2^6$ in original equation, we get

$2^2^{(x+3)}=2^6$

Distributing 2 over (x+3), we get

$2^{(2x+6)}=2^6$

Answer 2

 x-4/x3-64 Final result : x4 - 64x3 - 4 ————————————— x3
