To obtain an equivalent fraction by multiplying, multiply the whole fraction by any single number. Example: 3/4 multiplied by 3 is 9/12. Those fractions are equivalent.
To obtain an equivalent fraction by dividing, look at the top number and the bottom number. If they both can be divided by a number without it being a decimal, it’s an equivalent fraction. Example: 8/10, both of those numbers can be divided by 2 that isn’t a decimal, 4/5. 4/5 and 8/10 are equivalent
Answer: x = 1
Step-by-step explanation:
2log(x+1) - log (x+3) = log 1
log(x+1)^2 - log (x+3) = log 1
log [(x+1)^2 / (x+3)] = log 1
(x+1)^2 / (x+3) = 0
(x+1)^2 = 0
x = 1 or x = -1 (rejected, as log0 does not exist)
