Answer:

2x+8

Step-by-step explanation:

So when they say a number, they mean a unknown value.

We can use a variable as this unknown value. In this situration we can call it x.

This phase says "twice a number" or "twice x". This can be though of as 2x.

next it says this number is increased by 8. When they say increased they meanm added to.

So 8 is added to 2x. Or 2x + 8

So its the second answer, 2x+8.

Hope this helps!

Answer:

\sf \log_b(75)=4.317

\sf \ln (20)=2.9957

Step-by-step explanation:

<u>Question 1</u>

Given:

  \sf \log_b(3)=1.099

  \sf \log_b(5)=1.609

To evaluate \sf \log_b(75),  replace 75 with (5 × 5 × 3):

\implies \sf \log_b(5 \cdot 5 \cdot 3)

\textsf{Apply the Product log law}: \quad \log_axy=\log_ax + \log_ay

\implies \sf \log_b5+\log_b5+\log_b3

Substitute the given values to solve:

\implies \sf 1.609 + 1.609 + 1.099=4.317

<u>Question 2</u>

Given:

  \sf \ln(4)=1.3863

  \sf \ln(5)=1.6094

To evaluate ln(20) replace 20 with (4 × 5):

\implies \sf \ln (4 \cdot  5)

\textsf{Apply the Product log law}: \quad \ln xy=\ln x + \ln y

<em />\implies \sf \ln (4)+\ln (5)

Substitute the given values to solve:

\implies \sf 1.3863+1.6094=2.9957

Rewrite the expression with rational exponents as a radical expression by extending the properties of Internet exponents
Mekhanik [1.2K]

Answer:

option a

Step-by-step explanation:

y^7/8 / y^1/4

First we will accommodate the fractions

1/4 = 2/8

y^7/8 / y^2/8

Then we will subtract the exponents of the powers since they have the same base and are dividing

7/8 - 2/8 = 5/8

y^5/8

Finally we pass the 8 as radical root

8√y^5
