If x=5^a, find the value of 5x. How?

Yakvenalex [24]

Answer:

$5x = 5^{(a+1)}$

Step-by-step explanation:

Here is a problem with the concept of properties of the exponent.

We are given $x = 5^{a}$ and we have to find the value of 5x.

Now, $5x = 5 \times 5^{a}$ {Since we are given that $x = 5^{a}$ }

⇒ $5x = 5^{1} \times 5^{a}$ {Since we can write $x = x^{1}$ }

⇒ $5x = 5^{(a+1)}$ {Since we know the formula of exponent as $x^{m} \times x^{n} = x^{(m + n)}$ }

A 50 coat is put on sale for 35 <br> What percent is the decrease?

IRISSAK [1]

so the coat went down from 50 to 35, namely 15.

if we take 50 to be the 100%, what is 15 off of it in percentage?

$\bf \begin{array}{ccll} aount&\%\\ \cline{1-2} 50&100\\ 15&x \end{array}\implies \cfrac{50}{15}=\cfrac{100}{x}\implies \cfrac{10}{3}=\cfrac{100}{x} \\\\\\ 10x=300\implies x=\cfrac{300}{10}\implies x=30$
