Square root of 32 x square root of 1 over 18

lisov135 [29]

<h3>Solution:</h3>

$\sqrt{32} \times \sqrt{ \frac{1}{18} } \\ = \sqrt{32} \times \frac{ \sqrt{1} }{ \sqrt{18} } \\ = \sqrt{32} \times \frac{1}{ \sqrt{18} } \\ = \frac{\sqrt{2 \times 2 \times 2 \times 2 \times 2}}{ \sqrt{2 \times 3 \times 3} } \\ = \frac{ \sqrt{ {2}^{2} \times {2}^{2} \times 2} }{ \sqrt{2 \times {3}^{2} } } \\ = \frac{2 \times 2 \times \sqrt{2} }{3 \times \sqrt{2} } \\ = \frac{4 \times \sqrt{2} }{3 \times \sqrt{2} } \\ = \frac{4}{3}$

<h3>Answer:</h3>

$\frac{4}{3}$

Answer:

V = 9.828 * 10^7 mm^3

a= 9.828 b = 7

9,827,000 mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3 * 3.9*10^2 * 2.1*10^2

We multiply the numbers out front and add the exponents (the powers of 10)

V = (1.2*3.9*2.1) * 10^(3+2+2)

V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left. Since there is not enough places add zeros

9,827,000 mm^3
