If [tex]PHQ = R[/tex] and [tex]P - Q = S[/tex], then [tex]R^2 + S^2[/tex] is equal to:

Sagot :

Let's break it down step by step to solve for [tex]\( R \)[/tex] and [tex]\( S \)[/tex], and then compute [tex]\( R^2 + S^2 \)[/tex].

1. Given:
- [tex]\( P = 10 \)[/tex]
- [tex]\( H = 2 \)[/tex]
- [tex]\( Q = 5 \)[/tex]

2. Calculate [tex]\( R \)[/tex]:
[tex]\[ R = P \cdot H \cdot Q \][/tex]
[tex]\[ R = 10 \cdot 2 \cdot 5 \][/tex]
[tex]\[ R = 100 \][/tex]

3. Calculate [tex]\( S \)[/tex]:
[tex]\[ S = P - Q \][/tex]
[tex]\[ S = 10 - 5 \][/tex]
[tex]\[ S = 5 \][/tex]

4. Now, we need to find [tex]\( R^2 + S^2 \)[/tex]:
[tex]\[ R^2 = 100^2 = 10000 \][/tex]
[tex]\[ S^2 = 5^2 = 25 \][/tex]
[tex]\[ R^2 + S^2 = 10000 + 25 = 10025 \][/tex]

Therefore, the value of [tex]\( R^2 + S^2 \)[/tex] is [tex]\( 10025 \)[/tex]. This is the final result.
