d) -95 x 2 - (-95) x (-98)
e) (-51) x 102

Answer 1

Hii friend,

(a) (-16) × 75 × (-4) × (-5)

=> (-16×75) × (-4×-5)

=> (-1200) × (20)

=> -2400

(B) (-59) × (25) × (-10) × (-4)

=> (-59×25) × (-10×-4)

=> (-1475) × (40)

=> -59000

(C) 79 × (-99) + (-79)

=> (79×-99) - 79

=> -7821 - 79

=> -7900

(D) -95 × 2 -(-95) × -98

=> (-95×2) + (95×-98)

=> -190 + (-9310)

=> -190-9310

=> -9500

(E) (-51) × 102

=> -5202

HOPE IT WILL HELP YOU..... :-)
