The square root of (64/225) is the same as √64 / √225 .
That could make the whole thing easier.
Do you know what either of those separate square roots is ?
You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 .
You really know your stuff !
So now, the expression is √64 / √225 = <em>8 / 15</em> .
Oh, I almost forgot, it has a negative sign before it. OK,so the answer is <em>- 8/15</em> .
Step-by-step explanation:
We need to find an expression that is equivalent to 4×(8+3)
We know that,
4×(8+3) = 4(11) = 44
Option (1).
(4 • 8) + 3 = 32+3 = 35. It is incorrect
Option (2).
(8 + 3) • 4 = (11) 4 = 44. It is correct.
Option (3).
4 • (3 + 8) = 4(11) = 44. It is correct.
Option (4).
4 • 8 + 4 • 3 = 32+12 = 44. It is correct.
Hence, the correct options are (2), (3) and (4).
