Simplify the expression. Write the answer using scientific notation (4x10to the 11th)-2 square

6 years agoDoes it look this? \[(4\times10^{11})-2^{2}\]

6 years agoyes

6 years agoWhat are you having trouble with? The simplification or the scientific notation?

6 years agothe simplification

6 years agoDo you know how to simplify exponents?

6 years agonope

6 years ago\[3^{2}=3\times3=9\] \[4^{3}=4\times4\times4=64\]

6 years agodo you understand how I got these numbers?

6 years agoyou multiplied the, by the exponents

6 years agoBut if I multiplied the number by the exponents,\[4^{3}=12\]

6 years agothat's wrong

6 years agoWhat I did was multiply the base (the bigger number) t times(The little number is t)

6 years agobecause you are supposed to multiply 4 three times.

6 years agoexactly. Then what does \[2^{2}=?\]

6 years ago4

6 years agoand \[10^{11}=?\]

6 years agoor do you have trouble with that?

6 years agoI'm trying to figure that out. my calculator just keeps telling me 1e+11

6 years agoohhh

6 years agook. So what does 10x10=?

6 years agoand the 2to the -2 square was just a -2 as an exponent. No base

6 years ago100

6 years agoand then 10x10x10?

6 years ago1000

6 years agoSo you see that everytime you add one to your exponent, you add one zero, right?

6 years agoyup

6 years agoSo if your exponent is 10^11...

6 years agoexpression, rather

6 years agoIt would be 1 with 11 zeros behind it, or , 10000000000

6 years agoright?

6 years agoIf you just want the answer, it's \[6.25×10^{-24}\]
