Answer:
The correct option is 1.
Step-by-step explanation:
The given expression is
The value of a is 1 and the value of b is 1.
According to the logarithm property,
Using this property, we get
The required expression is 
.
![[\because log_aa=1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20log_aa%3D1%5D)
Left hand side is equal to the right hand sides, therefore option 1 is correct.
<span>4x+7=15
First step is to subtract 7 from both sides to get rid of it.
4x + 7 - 7 = 15 - 7
4x = 8
Now all you have to do is divide both sides by 4.
4x/4 = 8/4
x = 2
The answer is x = 2.</span>
Answer:
Step-by-step explanation:
x2 = 36?
solution
x^2-(36)=0
Factoring: x2-36
Check : 36 is the square of 6
Check : x2 is the square of x1
Factorization is : (x + 6) • (x - 6)
(x + 6) • (x - 6) = 0
x+6 = 0
x = -6
x-6 = 0
add 6 to both side
x = 6
x = -6
Answer:
15 dimes and 10 nickels
Step-by-step explanation:
15 dimes because 15 multiplied by 10 cents is $1.50
10 nickels because 10 multiplied by 5 cents is $0.50
15 x 0.10 = 1.50 10 x 0.50 = 0.50
0.50 + 1.50 = 2.00
