The correct way to solve the equation 4^x=128 if you do not know a power of 4 that equals 128 will be;

''Graph y = 4ˣ and y = 128, and look for points of intersection.''

Option A is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equations are,

⇒ y = 4ˣ and y = 128

Now,

We have to solve the equation as;

The equations are,

⇒ y = 4ˣ and y = 128

Since, You do not know a power of 4 that equals 128.

So, You can draw the graph of equation y = 4ˣ and y = 128.

By the image , we can see that both the equation intersect at point.

Which is the solution of the equations.

Thus, The correct way to solve the equation 4^x=128 if you do not know a power of 4 that equals 128 will be;

''Graph y = 4ˣ and y = 128, and look for points of intersection.''
