Question

help plz: nd clearly show steps to show how u did it: 
(7m^-4n^19) * (-9m^-14n^-6)

tkhunny · Answer

It is multiplication.  This is all you need $a^{b}a^{c} = a^{b+c}$,

anonymous · Answer

y but these are negative exponents..it's not tht easy, at first i thougt the same thing

tkhunny · Answer

Keep thinking it.  Who told you negative exponents worked differently?  Not so.  Just do it.

anonymous · Answer

oh. so, i just mutiply the coefficents and thn just add the exponents? For example, ^-4*^-14

tkhunny · Answer

Yup.  Let's see it.

anonymous · Answer

ok, SO my answer is :  -63m^-18n^-114
is that right?

tkhunny · Answer

Why did you ADD the m-exponents and MULTIPLY the n-exponents.  Both should be addition.

anonymous · Answer

oh, right, srry. i did tht by mistake, so rerwite/recap:   -63m^-18n^13

tkhunny · Answer

Now we're talkin'.  Good work.

anonymous · Answer

ok, so that's it? wow, pretty easy. thank you
