Show your work for the right answer

a^5 * a^4 / a^2

i do know that the answer is a^7 but i don't remember how to show my work to get the answer

= a^7

Step-by-step explanation:

Given in the question,

a^5 * a^4 / a²

To find,

show working

As we know that to divide exponents (or powers) with the same base, we subtract the exponents. Division is the opposite of multiplication, so when multiplying the exponents (or powers) with the same base add the exponents.

a^5 * a^4 / a²

= a^(5 + 4) / a²  (Multiplying)

= a^9 / a²

= a^(9 - 2)          (Dividing)

= a^7  

hence shown

which expression represents the approximate length of bc?

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
