Answer:

2x^11

Step-by-step explanation:

distributing x^8(2x^3) makes 2 * x^3 * x^8. To multiply exponents, just add the powers together to make 11. This makes 2x^11.

Answer:

8x^1^1

Step-by-step explanation:

Hi there!

x^8*(2x)^3

Distribute the exponent into the parentheses:

= x^8*2^3x^3\\= x^8*8x^3\\= 8*x^3*x^8

When two powers have the same base, add the exponents:

= 8*x^3^+^8\\= 8*x^1^1\\= 8x^1^1

I hope this helps!

Simplify the expression please.

Answer:

tanx·secx

Step-by-step explanation:

To simply this, you can begin by factoring sin x out of the numerator to become:

\frac{sinx (sin^{2}x +cos^{2} x)}{cos^{2} x}

Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:

\frac{sinx}{cos^{2}x }

First of all, we can convert \frac{sinx}{cosx} to tanx. However, we have a remaining \frac{1}{cosx} which, using reciprocal identities, will become sec x.

Finally, we get our answer as tanx·secx.

Rounding 16406.5 to nearest integer
kvasek [131]
<span>16407.

An integer is a whole number that doesn't need to be written using a fraction or decimals. (Some examples of integers are 4, 50, and -3; on the other hand, fractions or decimals like 1/2 or .3 are not).

Because we round up a number when the decimal is greater than or equal to .5 (which in this case it is), we round 16406.5 to the next biggest integer, 16407.</span><span />
