Question

would (3.6X10^5) x (7.2x10^7) come out to 25.92X10^12?

Answer 1

idk

Answer 2

\[(3.6*10{}^{\wedge}5) (7.2*10{}^{\wedge}7)=2.592*10{}^{\wedge}13 \]

Answer 3

rob , why would the decimal move?

Answer 4

gah. i dont even know why im second guessing your answer!

Answer 5

@savannahw88 it depends entirely on what canonical form you've chosen to represent the number. Since contextually it appears to be a scientific notation problem, you always want to keep a single whole part in the one's place.

Answer 6

\[25.92*10{}^{\wedge}12=2.592 * 10{}^{\wedge}13 \]

Answer 7

yes. scientific notation. sorry i wasnt specific.

Answer 8

well here it goes. I had five questions and just wanted to seek a second opinion on this last one. thanks guys. or gals.

Answer 9

np

Answer 10

wait one more double check. (-3p)^2 simplified is -3p^2.....

Answer 11

\[(-3p){}^{\wedge}2\text{ //}\text{Simplify} \to 9 p^2 \]

Answer 12

the same would go for (5p)^-2?

Answer 13

25p^2?

Answer 14

\[(5p){}^{\wedge}-2=\frac{1}{(5p){}^{\wedge}2}=\frac{1}{25 p^2} \]

Answer 15

is that because the exponent is negative?

Answer 16

Yes.
