'2aa4b' is a 5 digit number and when its divided by '36' it gives '11' as remainder. What is the sum of the values 'a' can have.

OverLord2011 [107]

The only 5-digit numbers that do the job are 21,143 and 28,847 .

So, either
a = 1 and
b = 3

or
a = 8 and
b = 7 .

The sum of the values that 'a' can have is (1 + 7) = <em>8</em> .

I shall cherish every one of your generous 5 points.

Hi, need help with solving this logarithm.

vfiekz [6]

Answer:

$\log 8 - \log x + 7\log\sqrt x =\log (8x^{\frac{5}{2}})$

Step-by-step explanation:

Given

$\log 8 - \log x + 7\log\sqrt x$

Required

Express as a single expression

We have:

$\log 8 - \log x + 7\log\sqrt x$

Write 7 as an exponent

$\log 8 - \log x + 7\log\sqrt x =\log 8 - \log x + \log(\sqrt x)^7$

Rewrite as:

$\log 8 - \log x + 7\log\sqrt x =\log 8 - \log x + \log(x^{\frac{1}{2}})^7$

$\log 8 - \log x + 7\log\sqrt x =\log 8 - \log x + \log x^\frac{7}{2}$

Apply quotient and product rule of logarithm

$\log 8 - \log x + 7\log\sqrt x =\log (\frac{8*x^\frac{7}{2}}{x} )$

Apply law of indices

$\log 8 - \log x + 7\log\sqrt x =\log (8*x^{\frac{7}{2} - 1})$

Solve exponent

$\log 8 - \log x + 7\log\sqrt x =\log (8*x^{\frac{7-2}{2}})$

$\log 8 - \log x + 7\log\sqrt x =\log (8*x^{\frac{5}{2}})$

$\log 8 - \log x + 7\log\sqrt x =\log (8x^{\frac{5}{2}})$

What is the value of the rational expression below when x is equal to 4? x-12/x-8

Firlakuza [10]

Answer:

When x=4 we get the value of the given expression is

$\frac{x-12}{x-8}=2$

Step-by-step explanation:

Given rational expression is $\frac{x-12}{x-8}$

To find the value of the given rational expression $\frac{x-12}{x-8}$

when x is equal to 4 :

That is the value of the given rational expression $\frac{x-12}{x-8}$

when x=4 :

$\frac{x-12}{x-8}$

Put x=4 in the above rational expression we get

$\frac{4-12}{4-8}$

$=\frac{-8}{-4}$

$=\frac{8}{4}$

$=2$

Therefore when x=4 we get the value of the given expression is

$\frac{x-12}{x-8}=2$
