Please first click on the image. the question :
If the pattern continues , what algebraic expression can be used to find the number of circles used in any figure ? how many circles will be in the 50th figure ?

Let the figure number be x.

Then the equation will be:

3x

There will be 3x circles in the figure number x.

So, number of circles in 50th figure will be

= 3(50)

= 3 × 50

= 150 circles

B

Step-by-step explanation:

You multiply the exponents when you are doing an exponent of an exponent. 8 * 8 is 64. Therefore, the answer is B.
