What value of n makes the equation true? (2x^9 y^n) (4x^2 y^10) =8x^11 y^20

n =10

Step-by-step explanation:

(2x⁹ yⁿ)(4x² y¹⁰)= 8x¹¹ y²⁰

2*4*x⁹*x²* yⁿ* y¹⁰= 8x¹¹ y²⁰

8x⁹⁺² * yⁿ⁺¹⁰ = 8x¹¹y²⁰

8x¹¹yⁿ⁺¹⁰ = 8x¹¹y²⁰

Now, compare the powers of y

n +10 = 20

n = 20 -10

n =10

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

i’m here for points.
