Given : (-3 + 3n⁵ + 6n³) + (7n⁵ + 5n³ - 3)

Rearrange respective Like terms as they are a Family, They should be together.

In the Given Expression, The Like terms are :

✿ 3n⁵ and 7n⁵

✿ 6n³ and 5n³

✿ -3 and -3

After Rearranging, The Given Question looks like :

✿ (3n⁵ + 7n⁵) + (6n³ + 5n³) - 3 - 3

Now, Add the Like Terms as they belong to the same Family

⇒ 10n⁵ + 11n³ - 6

Answer:

Step-by-step explanation:

-6 10n to the 5 11n to the 3

Use complete sentences to describe the relationship between the two sets A and B if A ⊆ B .

kakasveta [241]

Answer:

The relationship between the two sets A and B if A ⊆ B is A is subset of B

Solution:

A is subset of B means,” all elements of set A are present in set B”

Consider two sets A and B where ,

A = {1,2,3,4,5}

B = {1,2,3,4,5,6,7,8}

All Elements of set A {1,2,3,4,5} are present in set B

hence we relate set A and set B as A ⊆ B,which means set A is subset of set B. Symbol “⊆” is used to denote subset

So set A is subset of set B (A ⊆ B)

Find the value of yy in each equation. Explain how you determined the value of yy.

Answer:

a) 2

b) 5

c) -1

d) x

Step-by-step explanation:

We know the properties of log function as:

1) log(AB) = log(A) + log(B)

2) $\log(\frac{A}{B}) = \log(A)+\log(B)$

3) log(aᵇ) = b × log(a)

also,

4) $\log_b(a)=\frac{\log(a)}{\log(b)}$

Given:

a. y = log₂(2²)

thus, using 3

y = 2log₂(2)

or using 4

y = 2 × $\frac{\log(2)}{\log(2)}$

y = 2 × 1 = 2

b. y = log₂(2⁵)

thus, using 3

y = 5 × log₂(2)

or using 4

y = 5 × $\frac{\log(2)}{\log(2)}$

y = 5 × 1 = 5

c. y = log₂(2⁻¹)

thus, using 3

y = -1 × log₂(2)

or using 4

y = -1 × $\frac{\log(2)}{\log(2)}$

y = -1 × 1 = -1

d. y = log₂(2ˣ)

thus, using 3

y = x × log₂(2)

or using 4

y = x × $\frac{\log(2)}{\log(2)}$

y = x × 1 = x
