Answer:

Multiplication rule of exponents says $(xy)^n = x^n * y^n$ hence, 2^4 • 3^4 =6^4

Step-by-step explanation:

As per the rule of exponents,

$(xy)^n = x^n * y^n$

If we go by the above equation, we can deduce that x is 2 and y is 3

Thus, 2^4 *3^4 can be written as $(2*3)^4 = 6^4$

Hence, 2^4 • 3^4 =6^4

A class of 30 swim team members took a lifesaving test. Eighteen of the members had an average score of 92. The remaining member

andrew-mc [135]

Okay, so let's find the average
People with 92: 18(92)
People with 84: 12(84)
1656 + 1008 = 2664
So then we divide by 30
2664 / 30: 88.8
The average is a score of 88.8
