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 $x^{m} \times x^{n} = x^{(m + n)}$ }

If f(x) =3^x+10 and g(x) =4x -2 find (f+g)(x)

Valentin [98]

Answer:

$(f+g)(x)=3^x+4x+8$

if $f(x)=3^x+10$ and $g(x)=4x-2$ .

Step-by-step explanation:

We are given $f(x)=3^x+10$ and $g(x)=4x-2$ .

We are asked to find $(f+g)(x)$ .

$(f+g)(x)$ means $f(x)+g(x)$

$(f+g)(x)=(3^x+10)+(4x-2)$

You only have one pair of like terms, that is the constants.

$(f+g)(x)=3^x+4x+10-2$

$(f+g)(x)=3^x+4x+8$
