5*9 (sqrt 10)^3= Help please

Nikitich [7]

Use BODMAS or BIDMAS (Brackets, over Indices, Division, Multiplication, Addition, the Subtraction, this tells you which order to do things in)

As you cant do √10 in the brackets you do the indices, so (√10)³
Split this up to make it easier
(√10)³= √10 x √10 x √10 = 10√10

You the multiply this by 9

9 x 10√10 = 90√10

then multiply by 5

5 x 90√10 = 450√10 = 1423.024947 (using calculator)

The quotient 250/5/8 tells about how far a sloth may move in one hour. How far can a sloth go in 90 minutes?

VladimirAG [237]

$Answer: \text{Sloth covers }9\frac{3}{8}\text{in 90 minutes.}$

Explanation :

Since we have given that

$\text{in 1 hour sloth may move = }\frac{250}{5\times 8}$

$\text{ In 60 minutes , sloth may move = }\frac{25}{4}$

$\text{ In 1 minute, it may move = }\frac{25}{4\times 60}\\\\\text{ In 1 minute, it may move = }\frac{5}{48}$

$\text{ In 90 minutes, it may move}\\=\frac{5\times 90}{48}\\ \\=\frac{75}{8}\\\\=9\frac{3}{8}$

∴ $\text{Sloth covers }9\frac{3}{8}\text{in 90 minutes.}$
