Answer 2

• (-192)
• (-96)

ज्ञात करना है :- सरल कीजिए :-

• (-4) x (-6) x (-8)
• (-12) x (8)

उतर :-

(i) (-4) x (-6) x (-8)

→ {(-1) × 4} × {(-1) × 6} × {(-1) × 8}

(-1) को सभी में से common लेने पर,

→ (-1)(4 × 6 × 8)

→ (-1) × 192

→ (-192) (Ans.)

दूसरा तरीका :-

→ (-4) x (-6) x (-8)

→ {(-1) × 4} × {(-1) × 6} × {(-1) × 8}

→ {(-1) × (-1) × (-1)} × (4 × 6 × 8)

a^m × a^n × a^p = a^(m + n + p) का प्रयोग करने पर,

→ (-1)^(1 + 1 + 1) × (4 × 6 × 8)

→ (-1)³ × 192

अब हम जानते है कि, (-1)^n = (-1) यदि n = विषम संख्या हो,

→ (-1) × 192

→ (-192) (Ans.)

_________

(ii) (-12) × (8)

→ {(-1) × 12} × 8

चूंकि (a × b) × c = a × (b × c) होता है, अत,

→ {(-1) × {12 × 8}

→ (-1) × 96

→ (-96) (Ans.)
