Question

find the value of the expression 5 + s + t^u for s = 7, t = 1, and u = 2.

Explanation:

Step1: Substitute the values

Substitute \(s = 7\), \(t = 1\), and \(u = 2\) into the expression \(5 + s+t^{u}\). We get \(5+7 + 1^{2}\).

Step2: Calculate the exponent

Calculate \(1^{2}\). Since any non - zero number to the power of 2 is itself multiplied by itself, and \(1\times1=1\), the expression becomes \(5 + 7+1\).

Step3: Perform addition

Add the numbers together: \(5+7 + 1=(5 + 7)+1=12 + 1=13\).

Answer:
