The value of n which makes the exponential value equation true is n = 10
When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be A
Now , the value of A is
A = ( 2x⁹yⁿ ) ( 4x²y¹⁰ ) = 8x¹¹y²⁰
So , from the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
( 2x⁹yⁿ ) ( 4x²y¹⁰ ) = 8x⁹⁺²yⁿ⁺¹⁰
( 2x⁹yⁿ ) ( 4x²y¹⁰ ) = 8x¹¹yⁿ⁺¹⁰
And , the value of A is = 8x¹¹y²⁰
So , on simplifying , we get
8x¹¹y²⁰ = 8x¹¹yⁿ⁺¹⁰
y²⁰ = yⁿ⁺¹⁰
Since the bases are same , the powers are also same
20 = n + 10
Subtracting 10 on both sides , we get
n = 10
Hence , the exponential equation is solved and n = 10

Answer:
a)-5
Step-by-step explanation:
-(5-(a+1))=9-(5-(2a-3))
= -(5-a-1)= 9-(5-2a+3)
= -5+a+1 = 9-5+2a-3
= -4+a = 1+2a
= -4 - 1 = 2a-a
= -5 = a
