Come on TT - up late at night doing homework ? It must be in the chapter.
First factorise, whcih I can do in my head but never mind, 2 is factor and so is five,
2 x 5 x 48 and 48 is four tweves, so we get
2x 2 x 2 x 2 x 2 x 2 x 5 x 3 or something
this is also 2 to the 6 x 5 to the one times 3 to the one (or whatever)
and der daah the exponent of 2 is 6 and of five is one and of three is one.
Not very clear Ihave to say....
and also ambiguous
take sixteen 16, that is four squared that is the exponenet of 4 is two and is also 2 to the 4,and the exponent of 2 is four - and is for (!) the same number....
Nice, thank you. And no, it wasn't my homework but that of a friends son. Next time someone asks me 'were u any good at maths' i shall just drop everything and run away :)
Your question appears ambiguous to me and so I offer an alternative answer.
Numbers are often expressed in scientific notation (which also goes under other names such as 'floating point notation'). The number is expressed in 2 parts called the mantissa and the exponent.
In this case, the number 480 expressed in scientific notation is 4.8 E2
(where the mantissa is 4,2 and the exponent, E, is 2)
An exponent is the power to which a number is multiplied. It is usually signified by adding a small number (called a superscript, I think) to the side of the one to be multiplied, like in the 2 in the squared sign. So, 2� means 2 to the power of 3 - ie '2x2x2'; the exponent is 3.
