Nicole simplifies 2^a*2^5/2^b to 2^(a-b+5). Which two properties of exponents did she use while simplifying the expression?
A. Negative Exponent Property and Product of Powers Property
B. Quotient of Powers Property and Product of Powers Property
C. Quotient of Powers Property and Power of a Product Property
D. Negative Exponent Property and Power of a Product Property

D.

Step-by-step explanation:

2^a*2^5/2^b = 2^(a+5)/2^b. using power of a product property.

then

2^(a+5)/2^b= 2^(a+5)*2^-b. Using Negative Exponent property.

Again we can use power of a product property and we get 2^(a+5)*2^-b=2^(a-b+5)

£106.92

Step-by-step explanation:

for simple interest, we have:

where p is the principal - £990

r is the rate - 2.7%

t is the time - 4yrs

(990*2.7*4) / 100

10692 / 100 = 106.92
