What's the square of 10 to the power of 2

(√10)^-2 …

Now for the negative powers first of all make it positive for your convenience.

(√10)^-2=1/(√10)^2

Secondly , simplify the question …here we can see that

√10^2 in denominator thus….cancel the powers …ie (10)^(1/2*2)=10

great …you solved it now….1/10. Is what you get….now I think you know the answer ….Yes…it is.

0.1

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
