27 x 3 = 81
3X=9 x=9/3 x=3
To write 22,600,000 in expanded form using exponents, you would express it as 2.26 x 10^7. This is because 22,600,000 can be written as 2.26 multiplied by 10 raised to the power of 7. The exponent indicates how many times 10 is multiplied by itself, which in this case is 7 times.
The base is the large number, and is the number being multiplied; the exponent is the smaller number on the upper right, which says how many times the base is multiplied. 23 says that 2 is multiplied 3 times, so: 2 X 2 X 2. In this case, the base is 2, and the exponent is 3.
21 x 3 = 63
the 3 goes after the x and is superscript. This is how it looks: x3
for example, if you have 2x you can write it as : 2 times x or 2 multiplied by x.
243 x 3 = 729
A number, x, multiplied by itself once is x^2. It is NOT x.The number, x, multiplied by itself twice is then x^3.The number, x, multiplied by itself three times is then x^4.Thus x is the 4th root of 27.So x = 27^(1/4) = +/- 2.2795 and +/- 2.2795*i where i is the imaginary square root of -1.
Just like this: 3 X 5,000,000
If x is the number, thenx multiplied by itself once is x*x,x multiplied by itself twice is x*x*x,x multiplied by itself three times is x*x*x*x,So it is the fourth root of 125 = 3.3437, approx.
You write exponents by multiplying a number by itself. Some examples: 75 = 7 to the 5th power, which means 7 multiplied by itself 5 times: 7 x 7 x 7 x 7 x 7 = 16,807 83 = 8 to the 3rd power, which means 8 multiplied by itself 3 times: 8 x 8 x 8 = 512 126 = 12 to the 6th power, which means 12 multiplied by itself 6 times: 12 x 12 x 12 x 12 x 12 x 12 = 2,985,984
7 x 3 = 21 7 x 7 x 7 = 343
The exponent tells how many times the base is multiplied. 9^2 = 9 x 9 9^3 = 9 x 9 x 9
8 x 3 = 24 Eight times three equals twenty four. 8 multiplied by 3 equals 24 8 * 3 = 24 8 x 3 = 24 Eight times three equals twenty four. 8 multiplied by 3 equals 24 8 * 3 = 24
3 x 3 = 9 x 8 = 72 or 3 x 8 = 24 x 3 = 72
4.8 x 10-3
