Answer:

x = -9

Step-by-step explanation:

25^x = 125 ^(x+3)

Rewriting

5^2^x = 5^3^(x+3)

We know a^b^c = a^(b*c)

5^(2x) = 5^(3(x+3))

5^(2x) = 5^(3x+9)

The bases are the same so the exponents are the same

2x = 3x+9

Subtract 3x from each side

2x-3x = 3x+9-3x

-x =9

x = -9

Artist 52 [7]

Wittaler [7]

There was 25.37% error in calculations.

Step-by-step explanation:

Given,

Anticipated calories = Approx value = 50 calories

Actual calories = Exact value = 67 calories

Percent error = \frac{|aprrox\ value-exact\ value|}{exact\ value}*100

Percent error = \frac{|50-67|}{67}*100

Percent error = \frac{|-17|}{67}*100=\frac{17}{67}*100

Percent error = \frac{1700}{67}

Percent error = 25.37%

There was 25.37% error in calculations.
