Is the calculator always right?
It really depends on the calculator. As long as you make sure you punched in the right numbers. To check if your calculator is broken, press the number 8 and if some pieces of the corner of the number is faded, then it's time to buy a new calculator. yes it is always right just as long as you are typing in the right numbers that you need to. :) brandi
When using a calculator to find the square root of a number what is the correct sequence of steps?
Assuming you have a scientific calculator which has a square root button ([√]) the method depends upon which calculator you have, and in what mode the calculator is set. The most recent Casio calculators have two modes of entry: MathIO and LineIO. InMathIO the sequence is: [√] [<expression>] [=] In LineIO, if the <expression> is more than one number brackets needs to be entered: [√] [(] [<expression>] [)] [=] This LineIO type of entry is used on the older Casio calculators. With older models of Casio calculators, and other manufacturers the functions work on the displayed value which is replaced by the value if the function. With these calculators, the expression is entered first and then the square root key is pressed: [(] [<expression> [)] [√] parentheses are only needed if the square root is of an expression. Examples: Square root of 16 MathIO: [√] [1] [6] [=] LineIO: [√] [1] [6] [=] Other: [1] [6] [√] Using Pythagoras to find the hypotenuse of a right angle triangle with sides 3 and 4: MathIO: [√] [3] [x²] [+] [4] [x²] [=] LineIO: [√] [(] [3] [x²] [+] [4] [x²] [)] [=] Other:[(] [3] [x²] [+] [4] [x²] [)] [√] With MathIO the square root symbol extends over the expression as each key is pressed which is why the parentheses are not needed in the last example.
Is 310172431 arithmetic sequence?
Oh, dude, an arithmetic sequence is a sequence of numbers where the difference between consecutive terms is constant. So, to check if 310172431 is an arithmetic sequence, you'd need a sequence of numbers, not just one lonely number. Like, you can't have a party with just one person, right? So, in this case, 310172431 is not an arithmetic sequence because it's just a single number hanging out by itself, feeling all left out.
Where is the exponent key on a TI-30XA calculator?
Hit the EE button on the calculator, and two zeros pop up on the right side of the screen. You then can type any one or two digit number as your exponent.
What is the square root of 343?
Well, isn't that a happy little question! The square root of 343 is 19. You see, when you find the square root of a number, you're looking for a number that, when multiplied by itself, gives you the original number. Just like painting a beautiful landscape, math can be a peaceful and rewarding experience.
