Answer:

a - Original length = 18; b - Original length = 12; c - Copy length = 15, ratio = 2/3

Step-by-step explanation:

For part a, we know the ratio is 2/3. We also know the copy length is 27.

To change the denominator of the ratio to 27, we would multiply by 9; multiplying the top by 9, we have 2(9) = 18.

For part b, we know the ratio is 2/3. We also know the copy length is 18.

To change the denominator of the ratio to 18, we would multiply by 6; multiplying the top by 6, we have 2(6) = 12.

For part c, we only have one option left for the copy length; it must be 15.

This makes the ratio 10/15, which simplifies to 2/3.

A- Original length = 18
b- Original length = 12
c- Copy length = 15 ; Original Length/Copy Length = 2/3

Which of the below is not one of the properties of logarithms?

MrRa [10]

Answer:

option-B

Step-by-step explanation:

we know that

Sum rule of logarithm:

$log(a)+log(b)=log(a\times b)$

which is same as

the log of a product (ab) is equal to the addition of log a nad log b

Subtraction rule of logarithm:

$log(a)-log(b)=log(\frac{a}{b} )$

which is same as

the log of the quotient of a and b is equal to the log of a minus the log of b

Exponent rule of logarithm:

$log(a^b)=blog(a)$

which is same as

the log of the quantity a raised to b is equal to the product of b and the log of a

so,

option-B is not correct

The sides of a square are five to the power of two fifths inches long. How is that written in radical form?

Evgen [1.6K]

Remember
$x^ \frac{m}{n}= \sqrt[n]{x^m}$
so
$5^ \frac{2}{5}= \sqrt[5]{5^2}= \sqrt[5]{25}$
