Answer:

Keep the base the same and then subtract the exponents.

Step-by-step explanation:

According to one of the law of indices, for given values a, m and n;

a^m/a^n = a^(m-n)

The base value which is a is maintained and the difference of exponents are taken. In indices division becomes subtraction.

Now given the expression

3^-6/3^-4

As we can see, both the numerator and denominator has the same base which is 3, therefore we will keep the base and take the difference of its exponents according to the law above:

3^-6/3^-4 = 3^(-6-(-4))

= 3^(-6+4)

= 3^-2

= 1/3^2

= 1/9

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Tpy6a [65]

Answer:

55 = 5x

Step-by-step explanation:

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.

Write an equation to model this situation in the form y = mx + b, but do not

include any spaces in your answers. (for example y=6x+1)

Equation to model this situation in the form y = mx + b,

y = Total number of stickers she had

x = Number of days that she gave away sticker

b = Fixed value = 0

Hence:

55 = 5x + b

b = Fixed value = 0

Therefore, the situation is represented as:

55 = 5x
