Who has more money in their account? Response area

What is the difference in the amount of money that they have? Response area

Answer 1

To determine who has more money in their account and the difference in their account balances, we need to simplify each expression for Sama and Jimena.

Simplifying Sama's expression:

Sama: \[ \frac{5^8 \cdot 5^4}{(5^3)^2} \]

First, simplify the numerator: \[ 5^8 \cdot 5^4 = 5^{8 + 4} = 5^{12} \]

Now simplify the denominator: \[ (5^3)^2 = 5^{3 \cdot 2} = 5^6 \]

Putting it together: \[ \frac{5^{12}}{5^6} = 5^{12 - 6} = 5^6 \]

Calculating \(5^6\): \[ 5^6 = 15625 \]

Simplifying Jimena's expression:

Jimena: \[ \frac{2^9 \cdot (2^{-2})^{-3}}{2} \]

First, simplify the exponent in the numerator: \[ (2^{-2})^{-3} = 2^{-2 \cdot -3} = 2^6 \]

Now simplify the numerator: \[ 2^9 \cdot 2^6 = 2^{9 + 6} = 2^{15} \]

Now, simplify the entire expression: \[ \frac{2^{15}}{2} = 2^{15 - 1} = 2^{14} \]

Calculating \(2^{14}\): \[ 2^{14} = 16384 \]

Comparing their amounts:

Sama has \(15625\) and Jimena has \(16384\).

Responses:

1. Who has more money in their account?
   Jimena

2. What is the difference in the amount of money that they have?
   \[ 16384 - 15625 = 759 \]

Final Answers:

1. Jimena
2. 759
