Please don't give out direct answers :) @DecentNabeel Instead, try engaging the asker so they can learn better and understand where your answer is coming from. As the saying goes… \(\\\color{darkblue}{Give~a~man~a~fish,~he~eats~for~a~day.}\) \(\\\color{pink}{Teach~a~man~to~fish,~he~eats~for~a~lifetime.}\)

You sure, @DecentNabeel ?

@DecentNabeel Could be incorrect. You never know.

the highest power is the the largest number @keshaun455

so its d

and it is NOT D

If you want, multiply them all to make sure. :)

sorry i cant type fast i have to refresh my page to type
anonymous

remember the the number with the highest power is the the largest number

see what I drew to know where the power is. :)

when the value is expressed in scientific notation then look for the highest power, the n, as shown by @mathway above also.

@DecentNabeel your error was to use the greatest "a"
anonymous
  • anonymous
so im looking for the largest number
triciaal

need to compare the standard

When comparing scientific notation, first make sure that there is only one non-zero digit before the decimal point. For example: \[ 42.34\times 10^3 = 4.234\times 10^4\\ 0.035 \times 10^{-3} = 3.5\times 10^{-5} \]Once in this form, you only need to compare the exponents. For example \(-5<4\), so clearly the first number is greater than the second one. If the exponents are equal, then you just need to compare the numbers in front. For example: \[ 4.35\times 10^5\\ 4.36\times 10^5 \]The exponents are the same, but the second number is greater.

@keshaun455 is it clear now?

Moving the decimal point to the right decreases the exponent by one. Moving it to the left increases the exponent by one. For example: \[ 30.2\times 10^2 = (30.2 \div 10) \times(10^3\times 10) = 3.02\times 10^4 \]Dividing and multiplying by ten is the same as multiplying by \(1\).
