Question

log base 4* (1/16) = -2?

Answer 1

\[\log_{b} M = x\]
Same as:
\[b ^{x} = M\]
So in this case that would be correct because 4^(-2) does = 1/16

Answer 2

can I ask you to help with another?

Answer 3

Go for it.

Answer 4

Simplify... (Sin^3(x)+Cos^2(x)Sin(x))/(Sin^2(x))

=
Sin(x)(1+Cos^2(x))

Answer 5

is that correct?

Answer 6

Well, let's see.

Answer 7

I would say that it is not. Try factoring out a sinx from the numerator and see where that takes you.

Answer 8

\[\frac{ \sin ^{3}(x) + \cos ^{2}(x)\sin(x) }{ sinx }\]
This can become:
\[\frac{ sinx(\sin ^{2}x + \cos ^{2}x) }{ sinx }\]

Answer 9

is it 1?

Answer 10

Yep ^_^

Answer 11

you are the best :)
