The average age of a group of 13 boys is 13 when 2 more boys join the group. the average rose by 2 years the sum of the ages of two new boys

The sum of age of the  two new boys =   56 years

Step-by-step explanation:

The average age of a group of 13 boys = 13

The sum of age of the  13 boys = 13 * 13 = 169

The average age of a group of 15 boys  = 15

The sum of age of the  15 boys = 15 * 15 = 225

The sum of age of the  two new boys = 225 - 169 = 56 years

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!
