X * y = 50
y = 50 / x
S = x + y = x + 50 / x
S` = 1 - 50 / x²
1 - 50 / x² = 0
50 / x² = 1
x² = 50
x = √ 50 = 5 √2
y = 50 / 5√2 = 5 √2
Answer:
Those numbers are: x = 5√2 and y = 5√2.
v = 1
explanation:
-22 + 8v = 7(4v - 6)
distribute 7 into 4v - 6
-22 + 8v = 28v - 42
subtract 8v from both sides
-22 = 20v - 42
add 42 to both sides
20 = 20v
divide by 20 on both sides
1 = v
The answer is <span>2) (log5)3/(log5)8
</span>
We will use the change-of-base formula:

So, if we want to write <span>log8 3 as a logarithm of base 5, </span> in these example a = 8, x = 3, b = 5:
Answer:
81/15
Step-by-step explanation:
14/3 would become 70/15 and 11/5 would become 33/15 and 70+33 is 103, so 103/5. 103/15 - 22/15 = 81/15.
