Larissa argued that since log2(2) = 1 and log2(4) = 2, then it must be true that log2(3) = 1.5. Is she correct?
mestny [16]

Answer:

2^{1.5} = 2.8284. This means that Larissa is not correct.

Step-by-step explanation:

To solve logarithms, we have to consider the following:

\log_{a}(b) = c means that a^{c} = b.

So, for example:

log_{2}(2) = 1 because 2^{1} = 2.

log_{2}(4) = 2 because 2^{2} = 4.

If 2^{1.5} = 3, then Larissa is correct. However, 2^{1.5} = 2.8284. This means that Larissa is not correct.

the combined area of two squares is 45 square centimetres each side is twice as long as a side of the other square what length o
Ostrovityanka [42]

Answer:

Let the side of  one square be x.    Area = x*x = x²

Then the side of other square  would be 2x ,   Area = 2x*2x = 4x²

Combined area = x² + 4x²  = 5x²

This combined area = 45 cm²

you simplify

Therefore  5x²  = 45   Divide both sides by 5

                 x²  =  45/5

                 x²  = 9        Take square root of both sides

                 x   =  √9

                 x  = 3

Length of larger square is 2x  = 2*3 = 6 cm

Length of larger square = 6cm
