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) = 9x - 2 and g(x) = 2x², what is the value of f(4) - g(4)
pishuonlain [190]

9514 1404 393

Answer:

  f(4) -g(4) = 2

Step-by-step explanation:

Fill in the given values for x and do the arithmetic.

  f(4) = 9·4 -2 = 34

  g(4) = 2·4^2 = 32

Then ...

  f(4) -g(4) = 34 -32

  f(4) -g(4) = 2
