Answer:
2![\sqrt{8}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D)
Step-by-step explanation:
According to Euclidian theorem :
h^2 = 4*8
h^2 = 32 find the root for both sides
h = 2![\sqrt{8}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D)
Answer:
61 3/5
Step-by-step explanation:
we realize that 8 4/5 can be written as [8 + (4/5)]
hence 7 x 8 4/5
= 7 x [8 + (4/5)]
= 7 [8 + (4/5)] (use the distributive property, see attached for reference)
= 7(8) + 7(4/5)
= 56 + 28/5 (convert 28/5 into mixed fraction)
= 56 + 5 3/5
= 61 3/5 (answer)
415529284.606 is the correct answer
