Question

7⁵•7² = 7⁵+² =7⁷
(5:2)⁷ =5⁷ : 2⁷​

Answer 1

Resposta: d) (-1/4)⁻² = 16 e) (5/2)⁻³ = 8/125 ... a) 5⁷ . 5² = 5⁹ (v) b) 3⁹ : 3⁴ = 3⁵ (v) c) 8⁵ : 8⁻³ = 8² (f) d) 7⁵ – 7³ = 7² (f) e) 7⁶⁻⁵ = 7⁶ / 7⁵ (v) ... 7)⁵ . ( 3 .7 )² = 3⁷ . 7⁷ b) (​5xy²) . (2x²y³) = 10x³y⁵ c) ( a² . b)² . (a . b)³ = a⁷ . b⁵ d) (7xy²)² .
