Select all of the potential solution(s) of the equation 2log5x = log54.
Vanyuwa [196]

Answer:

x = ±2

Step-by-step explanation:

A equation is given to us , which is ,

\longrightarrow 2log_5(x) = log_5 4

From <u>properties </u><u>of </u><u>logarithm </u>we know that ,

\longrightarrow alog\ m = log \ m^a

Applying this to LHS , we have ;

\longrightarrow log_5 x^2 = log_5 4

Now the bases of logarithm on LHS and RHS is same . On comparing , we have ;

\longrightarrow x^2 = 4

Put square root on both sides,

\longrightarrow x =\sqrt{4}

Simplify ,

\longrightarrow \underline{\underline{ x =\pm 2 }}

This is the required answer.

There is 3/4 of pizza leftover from the night before . how many 1/8 portions are there
serg [7]
We want to know how many 1/8's are in 3/4, so we divide.

\sf\dfrac{3}{4}\div\dfrac{1}{8}

Flip the 2nd fraction and multiply:

\sf\dfrac{3}{4}\times\dfrac{8}{1}

Multiply the numerators and denominators together:

\sf\dfrac{3\times8}{4\times1}\rightarrow\dfrac{24}{4}

Divide:

\boxed{\sf6}

How is adding mixed numbers with unlike denominators the same as adding fractions with unlike denominators? How is it different?
Sedaia [141]
To add a mixed number you must first convert it into a heavy headed fraction eg. 12/4
Then you must find a common denominator for all of the fractions like you normally do for regular addition of fractions
After you have added them you must convert the heavy headed fraction back into a mixed number by seeing how many times the numerator goes into the denominator
