Step-by-step explanation:

Geometric mean formula

I use the following formula to calculate the geometric mean: (Second Image)

Where n is the total number of values and xi (x2, x1, ... ,x n) are the individual numbers in the data set. The formula is equivalent to: (First Image)

In other words: It's the nth root of the product of n values.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
