Answer:

The equation is ⇒ 7( x - 0.75 ) = 2.8

The normal price of one cookie = $1.15

Step-by-step explanation:

Let the normal price is x

So, the cost of cookie today is x - 0.75

The price of 7 of them will be $2.8

So the equation will be:

<u> 7( x - 0.75 ) = 2.8</u>

Solve for x:

x - 0.75 = 2.8/7 = 0.4

x = 0.4 + 0.75 = 1.15

A x = 0

using the law of exponents a^{0} = 1

for (6² )^ x = 1 then x = 0

B note that 6^{0} = 1 ⇒ x = 1

2 → 2^8 × 3^(-5) × 1^(-2) × 3^(-8) × 2^(-12) × 2^(28)

= 2^(8 -12 + 28) × 1 × 3^(- 5 - 8)

= 2^24 × 3^(- 13) = 2^(24)/3^(13) = 10.523 ( 3 dec. places)
