Answer:
Forty-eight is 6 times greater than 8.
Step-by-step explanation:
Option 1: WRONG
6 times greater than 48
= 6 × 48
= 288
288 no equal to 8.
Option 2: WRONG
8 times greater than 48
= 8 × 48
= 384
384 no equal to 8.
Option 3: CORRECT
6 times greater than 8
= 6 × 8
= 48
48 is equal to 48.
Option 4: WRONG
8 times greater than 8
= 8 × 8
= 64
64 no equal to 48.
Option 1 : -22
using formula
(a + b )(a - b ) = a^2 - b^2
(√10 + 2√8) (√10 - 2√8)
= (√10)^2 - (2√8)^2
= 10 - 2×2×8=10-32
= -22
