Question

y=5^x (read as 5 to the x power) what is the value of y when x is -2

Answer 1

Answer:

$\frac{1}{25} = 0.04$

Step-by-step explanation:

$y=5^{x}$ when x = -2,

$y = 5^{-2}$ ans this can also be written as:

$y = \frac{1}{5^{2} }$

$y = \frac{1}{25} = 0.04$

Answer 2

Answer:

the answer would be 1/25 or 0.04

you first apply the exponent rule then simplify
