Question

Y=f(x)=5^(x) find f(x) when x = 3

Answer 1

Hello!

Answer:

`\Large \boxed{\sf 125}`

Explanation:

→ We want the value of f(x) when x = 3:

`\sf f(x) = 5^x`

→ We have just to replace x by 3:

`\sf f(3) = 5^3`

→ Simplify the function:

`\sf f(3) = 5^3 = 5 * 5*5 = \boxed{\sf 125}`

So, when x = 3, the function f(x) is equal to 125.

Answer 2

given ::

• 
  `f(x)=5^(x)`

to find ::

• 
  `f(3)=??`

by substituting ::

↣
`f(3)=5^(3)`

↣
`f(3)=5*5*5`

↣
`f(3)=125`

therefore ::

• f(3) = 125

`\rule{200}{3}`
