can you give me the explanation please ! this is my retrice

anonymous · Answer

I can give an answer but not so well of an explanation.

anonymous · Answer

why ?

anonymous · Answer

Because Math questions I get from Mathway.com, but if you want and explanation I would try looking at Khan academy they give amazing explanations.

anonymous · Answer

ok. thanks :)
but what is your answer?

anonymous · Answer

Well, If it is 9^10 x 27^20 it can not be calculated. https://mathway.com/

anonymous · Answer

why ? :(

anonymous · Answer

can you explain with me why i cant simplify this :(

miracrown · Answer

You could just type it into you calculator and get an answer, or we can mathematically break it down into smaller, more manageable parts than into a whole

miracrown · Answer

When you insert this into the calc:
 $$9^{10} \space \times 27^{20} \space = 	1.4780883e+38$$

miracrown · Answer

the E+38 means go 38 decimal places to the right

miracrown · Answer

We can break it down as well, I'll help you with the start ...
We want to break 9 down into parts, we can do this as such
9 is 3 times 3 or 3^2

miracrown · Answer

So how could we do this for 27? $$(3^2)^10*(?)^20 $$

miracrown · Answer

Where the question mark is where 27 is so how can we then proceed to break that down into parts of maybe 3? @Loonie

anonymous · Answer

what?

anonymous · Answer

what is the break parts of 27 ?

anonymous · Answer

its (3)^3

mrnood · Answer

whoaaa - do not rush to put numbers on this

9 = 3^2
27 = 3^3

Us the properties of indices to simplify the expression to a simple 3^x

anonymous · Answer

Nicely done MrNood

anonymous · Answer

how can i explain to my prof ?
