Question

please fully slove these ​

Answer 1

(1) (a) (-2)³ × (-2)⁵ = (-2)^3 + 5 = (-2)⁸

(b) (-3)³ × (4)³ × (-4)³

= (-27) × 64 × (-64)

= 110592

(c) a⁴ × a^-6 = a^4 + (-6) = a^-2

(d) x⁵ × x^-3 = x^5 + (-3) = x²

(e) 5³ ÷ 5^-3 = 5^3 + (-3) = 5⁰ = 1

(f) 2⁵ × 2^-4 ÷ 2²

= [ 2^5 + (-4) ] ÷ 2²

= 2¹ ÷ 2²

= 2^-1

= ½
