Answer:

Therefore, Option 1st is correct.
Step-by-step explanation:
We have given that a=1 and b=1
We need to find expression equivalent to the given expression
We have:
We have a logarithmic property:
(1)
Here, we have m=a, x=y and n=b on substituting the values in (1) we get:

Therefore, Option 1st is correct.
And when a=1 and b=1 we get:

Answer:
$165 Hope this helps! May I have brainliest? I need to level up?
Step-by-step explanation:
To find the original price before the increase, divide the new price by 1 + the percent of increase.
198 / 1.20 = 165
The original price was $165
Answer:
a = 40
Step-by-step explanation:
This is a multi-step equation using the distributive property and rational coefficents (fractions). The first step is to complete the distributive property on both sides of the equation and multiply each term in the expression in parenthesis by the constant on the outside. (3/4 x 2a) - (3/4 x 6) +1/2 = (2/5 x 3a) + (2/5 x 20). When we multiply and simplify, we get 3/2a - 9/2 + 1/2 = 6/5a + 8. Next step is to combine like terms: 3/2a - 8/2 = 6/5a +8. We then need to isolate the variable by using inverse operations: 3/10a = 12, then solve for 'a' by multiplying both sides by the reciprocal (10/3) to get a = 40.
Answer:
7.5
