what is it that you need help with on this?
I'm not good at multiplying more than two numbers with exponents.
You can take it two numbers at a time. Calculate the first two, then multiply the product by the third
2^8= 256 3^-5= 0.004115226337 then I multiply the two 1.053497942272
Everything multiplied by 0 is 1 so it'd be that
you've got it so far
Then exponent -2 = 0.901016235548
Looks good to me. I would say focus on the denominator of the fraction next, since its not going to be inverted by a negative exponent
Then the fractions/dividing would mean to subtract 3^-2 and 2^3
-7.8 repeated multiplied by 0.901016235548 = -7.10801969323
Exponent 4 = 2552.665000315
2^28 = 268,435,456
Okay wait, stop How did you get the -7.8 repeated?
By subtracting the numbers in the fraction
3^-2=0.1 repeated and 2^3 is 8
yes, but they do not have the same base, so I don't think subtracting would work here.
What should I do?
instead of subtracting the two numbers, divide them. You already calculated their values, so it shouldn't be that difficult. Also, the exponent 4 applies to the end result of the fraction ONLY, not after the fraction has been multiplied with the rest of the equation. There are parenthesis around the fraction, the exponent 4 applies to that set of parenthesis, if that makes sense
3^-2 is over 2^3, so I divide? 0.01389 repeated
now apply the exponent 4 to 0.01389 repeated
Then the exponent 4 makes it 3.7*10^-08 (I'm going to start rounding the numbers )
Then the 2^38 makes it 9.9 or 10
Now multiply that with the first number we had from the first set of parenthesis finally, multiply the product you just got by 2^28 After that, you should have your answer
is it 2^28 or 2^38? Be careful, that could really screw you over
The last exponent is 2^28
So the answer would be 10.9 or 11
Okay. You think you got it now? A lot of the times you may feel like you have no clue what you're doing when really all you need to do is break it down number by number
Thank you so much @ElyssaC
