Which of the following is in scientific notation(multiple/none can be scientific): a.1.59x10^6 b.6.78900x10 c.7.65x1^10 d.9.9x10^9
A and D
Bob thinks 3^2 X 3^3=3^5 and Joe thinks 3^2 X 3^3=3^6. Who is right and why?
Bob is right because when you multiply two exponents when the bases are the same, you ADD the exponents NOT MULTIPLY them.
What is the most efficient way to find a square root of a number that is not a perfect square?
Find the factor that is the largest perfect square, and rewrite the radical as the product of the perfect square and its other product.
Can you simplify 2x^3+2x^4?
No
Does root 9 plus root 9 equal root 18?
No
Does 22x^4/22x^-4=1? Why or why not
No, because the negative exponent means you move the 22x^-4 to the numerator, not just dividing 22x^4 by itself
Can you simplify y/3? Why or why not?
No, because there are no same bases you can subtract the exponents from.
Does root 9+ root 9= 9? Why or why not?
No, because you are adding the square roots, not multiplying them to get the square. Square root 9=3, and 3+3=6, whereas Square root 9 x 9 = 9 because 3x 3 = 9.
Can you simplify a^b+c^d? Why/Why not?
No, because you cannot add the exponents when the bases are not the same.
What is the purpose of scientific notation
To be able to write really long numbers without writing all of the digits
Does 6^6/6^2 equal 6^4? Why or why not?
Yes because when you divide two numbers with the same base, you subtract the exponents.
Is root 9 x root 9 = 9? Why or why not?
Yes because you are multiplying a number by itself, and any number multiplied by itself will be a square. Since 9 is a square, when you multiply 3( root 9) by 3(root 9) you get 9.
