What is the solution of log, 729= 3?<br> Of<br> 18<br> 81

Reptile [31]

Answer:
Solution
Step-by-step explanation:
Rewrite logx729= 3 is an exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)= y is equivalent to b^y = x.
X^3 = 729
Take cube root on both side and we get
x= 3√729
now we firstly simplify the 3√729
Rewrite 729 as 9^3
x = 3√9^3
pull terms out from under the redical, assuming positive real numbers
x=9
verify each of the solution by substituting them into logx729=3 and solving.
x= 9

Harper knows he is 50 yards from school. The map on his phone shows that the school is 2/3 inch from his current location. How f

lorasvet [3.4K]

Actual distance of the Harper from the school = 50 yards.

According to map the distance from the school = 34 inch.

We could say 34 inches represents 50 yards.

So, 1 inches could be represented by 50/34 = 25/17 yards.

In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.

Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately.

Therefore, Harper from home is 4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.

Solve mathematics question, please:) Unanswered re-asked question.

Fiesta28 [93]

Remember you can do anything to an equation as long as you do it to both sides

and when multiply by negative, flip sign

8+h>2+3h
minus h both sides
8+h-h>2+3h-h
8+0>2+2h
8>2+2h
minus 2 both sides
8-2>2-2+2h
6>0+2h
6>2h
divide by 2 both sides
6/2>2h/2
3>1h
3>h
