Answer: The answer you get for "1000(99-70 √2)" isn't the same as "1000(99-70 * 1.4)"
Step-by-step explanation:
1000(99-70 √2) =
1000×99+1000×−70√ 2 =
99000+1000×−70√ 2 =
99000−70000√ 2
1000(99-70 * 1.4) =
1000(99-98) =
1000* 1 = 1000
Even if 1.4 is an estimated answer for √2 but that's all it'll be, an estimation not an exact number. Hope this helps!!
