Answer:

14^10/14 to the tenth

Step-by-step explanation:

When dividing numbers that are the same with an exponent, you subtract the exponents. 15 - 5 = 10. Therefore, the answer is 14^10/14 to the tenth.

Hope this helps!

Answer:

${ \underline{ \sf{\int\limits^2_1 {x^{2}-8x+8 } \, dx} \: = \: - 1}}$

Step-by-step explanation:

${ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\ \\ = { \tt{[ \frac{ {x}^{3} }{3} - 4 {x}^{2} + 8x ] {}^{2} _{1}}}$

Substitute x with the limits:

$= { \tt{( \frac{ {2}^{3} }{3} - 4( {2)}^{2} + 8(2)) - ( \frac{ {1}^{3} }{3} - 4( {1)}^{2} + 8(1)) }} \\ = { \tt{( \frac{8}{3} - \frac{11}{3} )}} \\ \\ = { \tt{ - 1}}$

Factor by grouping step by step 7c^4-4c^3+28c^2-16c

matrenka [14]

After factor by grouping $7c^4-4c^3+28c^2-16c$ we get $c(7c-4)(c^2+4)$

Step-by-step explanation:

We need to factor the term:

$7c^4-4c^3+28c^2-16c$

Taking c common:

$7c^4-4c^3+28c^2-16c\\c(7c^3-4c^2+28c-16)$

Now making groups:

$c(7c^3+28c-4c^2-16)$

Now factorizing by groups:

$c(7c^3+28c-4c^2-16)\\=c(7c(c^2+4)-4(c^2+4))\\=c((7c-4)(c^2+4))\\=c(7c-4)(c^2+4)$

So, after factor by grouping $7c^4-4c^3+28c^2-16c$ we get $c(7c-4)(c^2+4)$
