Hi silverpuma;
9^4 compared to 5^6 instead of manually working out without a calculator
For small ones like 9^4 and 5^6, I think multiplication is fastest. Or you could use the exponentiation key.
You could use logarithms but I would not say that is easier.
Thanks Bobbym, I'll google the exponentiation key....
Hi all, I was wondering if there is a quick way of answering a test question I had tonight. I'm just beginning out learning Math so things are at the basic level.
The question was to order 10 numbers like 2^4, 5^3, 7^2, 3^5, 9^2 etc in a list beginning with the one having the smallest value. I did the multiplication and got them all right but I was wondering if there is a easy/quick way of getting the answer of say for example, 9^4 compared to 5^6 instead of manually working out without a calculator 9x9x9x9 / 5x5x5x5x5x5. Thanks in advance
I'm a mature student aged 52 left school with zero qualifications. But am now just beginning to teach myself GCSE Maths. This has grown out of helping my 10 yr son with his maths as he prepares for the equivalent of the old 11+/transfer exam (I'm from N Ireland). I'm amazed how much I love exploring this new world of numbers. For my leisure and bedtime reading its now prime Factors or negative numbers instead of, well anything rather than maths....!! I "think" I may have reasonably good but basic numeracy skills (began and ran 3 successful business etc).
I'm beginning at 10-11 year old level to make sure I have the foundation correct and then move swiftly to GCSE maths level. I'll be learning at home so I need to teach myself through helps and books and website etc. So I have a number of websites saved of the video and text varieties and this is the one I come back to all the time. Your clear explanations are wonderful. So from a grateful old codger like me please accept my appreciation :-)
