I used a calculator for these problems. If you really wanted to, you could use exponent properties (multiplication adds the exponents of 10 and division subtracts the exponents of 10) to figure out to what power 10 will be raised to in your head. But for the other numbers, I'd use a calculator.
Doing all the steps together (using parenthesis to separate and organize the problem) on a scientific calculator is ideal! And remember to not round your answers until the very end. You may find that with a phone calculator, it is much harder to keep track of complex equations, and often is not as accurate due to rounding error with each step!
Hi! I definitely agree with everyone that a graphing/scientific calculator will definitely be handy. Other than paying close attention to what you put into the calculator (so you don't mistake a number or miss a button), Lavelle suggested that we should try and predict - understandably harder for these kinds of equations - what the outcome will be. This way, if you miss something, it will hopefully be kind of obvious and you can try again/review your input.
Yes, you should used a scientific or graphing calculator to solve those problems. In order to get an accurate result try putting the entire problem in the calculator and use parenthesis correctly. It is important to place the parenthesis in the correct place, to avoid getting the wrong result.
Yes, I would definitely use a calculator for problems like that! Please keep in mind that it is extremely important to use parentheses when you are solving those types of problems. It will help you get an accurate result!!
I would use a calculator for sure! You could do it by hand for sure, but of course using the calculator saves so much more time, especially if it were on a midterm or final. Don't forget to check your parentheses when inputting the equation!
