Question

Which equation is equivalent to 4^x+3 = 64?

Answer 1

Answer:

4^x+3= 64

4^x+3=4^3

x+3=3 ( because if bases are equal we can equal powers)

x= 3-3

x=0

Answer 2

The value of x is equal to "zero (0)".

Step-by-step explanation:

We have,

$4^{x+3}$ = 64

To find, the value of x = ?

∴ $4^{x+3}$ = 64

⇒ $4^{x+3}$ = $4^3$

Comparing the power of 4, we get

⇒ x + 3 = 3

⇒ x = 3 - 3

⇒ x = 0

Thus, the value of x is equal to "zero (0)".
