anonymous · Answer

i don't even know, i'm so confused :(

shinalcantara · Answer

$$(2.3 \times 10^{-4})(5 \times 10 ^{-10})^{-11}$$
is this the expression given?

anonymous · Answer

yes

shinalcantara · Answer

oopss.. something's wrong with the answers or must have been the given.. you see when an exponent is raised to another exponent you only have to multiply.. you will have (-10)(-11)=110 and it's freakin' far from the choices even if we try to do the next operation involving the exponent -4

anonymous · Answer

i'll just choose the highest answer :)
