Question

Simplify the following expression completely: (-2 y^19)^4

Answer 1

This is just power of powers (I hope I got that right) and the distributive property. :)

Answer 2

\[(-2y ^{19})^4\]

Answer 3

\[=-2^4 *y ^{19*4}\]

Answer 4

@noemi -- Does that help a bit?

Answer 5

no i don't understand

Answer 6

Okay, well, what exactly don't you understand?

Answer 7

are you sopose to times the 19 and 4 and put it \[-2^4*y76\]

Answer 8

or is it going to be \[-2y^80\]

Answer 9

When you have an exponent raised to another exponent, the two exponents are multiplied, if that makes sense.

Answer 10

\[(y ^{19})^4 = y ^{19(4)} = y ^{76}\]

Answer 11

And since -2 is in front of the y, you are also going to raise it to the 4th power.

Answer 12

so you would multiply 4*76 =304 so my problem would be\[-2y^3^0^4\]

Answer 13

\[-2y^304\]

Answer 14

\[(-2y ^{19})^4 = -2^4*y ^{19*4} = 16y ^{76}\]

Answer 15

The 76 doesn't get multiplied by anything.

Answer 16

oh make sense

Answer 17

Try another one. :) I'll just make up something.

Answer 18

\[(-5x^7)^6\]

Answer 19

its\[-78125x^42\]

Answer 20

Your x exponent is right; the constant isn't. o:

Answer 21

\[-5^6 = 15625\]

Answer 22

oh ur right i multiplied the wrong one

Answer 23

\[(4z^19)^4 = 256z^76\]
