Answer:

Step-by-step explanation:
Here is a problem with the concept of properties of the exponent.
We are given
and we have to find the value of 5x.
Now,
{Since we are given that
}
⇒
{Since we can write
}
⇒
{Since we know the formula of exponent as
}
(Answer)
C+s=48
2c+4s=134 ⇒ c+2s=67
subtracting the equations, we get, s=67-48=19,
so, c=48-19=29
