How do you solve log x = 4?

Answers

Answer 1
Answer:

x = 10,000

log x = 4

Note that the natural base is 10. Therefore,

log₁₀x = 4

10⁴ = x

x = 10×10×10×10

x = 10000

Answer 2
Answer: In order to solve this, We will want to change it into an exponential form. Assuming that since we do not have a number beside log, It will be log base 10.


10^4=x

We can now solve for x.

This means that x= 10,000

X^2−1.78x, if x=2.78

Answers

Answer:

2.78

Step-by-step explanation:

We are given the expression x^2-1.78x

As we know that x=2.78, we can plug that value into the expression and simplify it

(2.78)^2-1.78(2.78)\n\n7.7284-4.9484\n\n2.78

The coordinates of the vertices of ANGLE PQR are P(-3,3), Q(2,3), and R(-3,-4). Find the side lengths to the nearest hundredth and the angle measures to the nearest degree.

Answers


Answer: PQ=5, QR=radical 61= 7.81, angle: 50degrees,Why:PQ=|-3|+2=5PR=6angle Alfa, so there is right angle triangle PQR so I can use following formula:PQ^2 + RP^2=QR^2;25 + 36=QR^2;QR=radical 61also I can use: sinus (angle)=PR/QR;sin(angle)=6/radical61=0.76822 which gives angle to be little bit more than 50 degrees{sinus 50 degrees=0,7660}.
