kari74 [83]

You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

log_3(14) \approx 2.402

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = log_a(c)

Some properties of logarithm are:

log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})

<h3>Using the above properties</h3>

log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771  = log_3(14)\\\\log_3(14) = 2.402

Thus,

The approximate value for given term is given by

log_3(14) \approx 2.402

Ho do you get the Surface Area of this shape?
blsea [12.9K]
This solid object contains 8 sides.

The side that is facing you has a surface area:

64f{ t }^{ 2 }+84f{ t }^{ 2 }=148f{ t }^{ 2 }

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

84f{ t }^{ 2 }

The side to your right has a surface area:

84f{ t }^{ 2 }

The side to your left has a surface area:

48f{ t }^{ 2 }

The side to your top left has a surface area:

48f{ t }^{ 2 }

The side beside the side to the top left has a surface area:

36f{ t }^{ 2 }

The side at the very top has a surface area:

36f{ t }^{ 2 }

Combined, the surface area is:

S=2\cdot 148f{ t }^{ 2 }+2\cdot 84f{ t }^{ 2 }+2\cdot 48f{ t }^{ 2 }+2\cdot 36f{ t }^{ 2 }

\\ \\ =296f{ t }^{ 2 }+168f{ t }^{ 2 }+96f{ t }^{ 2 }+72f{ t }^{ 2 }\\ \\ =632f{ t }^{ 2 }

Therefore the answer is: C
