Question

(y2)5

Answer 1

i meant (y^2)^5

Answer 2

can you help

Answer 3

Remember exponent rules? One of them is \(\Large (A^b)^c = A^{bc}\)

Answer 4

oh so just times the exponents

Answer 5

so y^10

Answer 6

Or you could rewrite \((y^2)^5 = (y^2)(y^2)(y^2)(y^2)(y^2)\)

Yeah basically you multiple the exponents.

Answer 7

yeah. y^10

Answer 8

okat thanks what about (y^2)(y^5)

Answer 9

\((y^2)^5 = (y^2)(y^2)(y^2)(y^2)(y^2) = y^{2+2+2+2+2} = y^{2\cdot 5} = y^{10}\)

for second problem, another rule states that \(\Large A^bA^c = A^{b+c}\)

Answer 10

So just add the exponents.

Answer 11

You get it?

Answer 12

was is expanded form

Answer 13

what
