1 answer:
Answer:
2 over 5 and negative 2 over 5
Step-by-step explanation:
4 - 25x power2 = 0
(left side) (right side)
first we let the 25 power 2 go to the right side because the 25x power 2 is negative form at left side so when it go to the right side it will become positive form, so :
4 = 25x power 2
now we let the 25 go back to the left side again and this time it will become :
4 over 25 = x power 2
and now we can let the power 2 go to the left side and it will become square root :
+ - √ 4 over 25 = x
at the end, you will get 2 answers which is 2 over 5 and negative 2 over 5.

The rule we use here is
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
